The AD9761 is a complete dual channel, high speed, 10-bitCMOS DAC. The AD9761 has been developed specifically foruse in wide bandwidth communication applications (e.g., spreadspectrum) where digital I and Q information is being processedduring transmit operations. It integrates two 10-bit, 40 MSPSDACs, dual 2x interpolation filters, a voltage reference, anddigital input interface circuitry. The AD9761 supports a20 MSPS per channel input data rate that is then interpolatedby 2x up to 40 MSPS before simultaneously updating eachDAC.The interleaved I and Q input data stream is presented to thedigital interface circuitry, which consists of I and Q latches as wellas some additional control logic. The data is de-interleaved backinto its original I and Q data. An on-chip state machine ensures theproper pairing of I and Q data. The data output from each latch isthen processed by a 2x digital interpolation filter that eases thereconstruction filter requirements. The interpolated output of eachfilter serves as the input of their respective 10-bit DAC.The DACs utilize a segmented current source architecture combinedwith a proprietary switching technique to reduce glitchenergy and to maximize dynamic accuracy. Each DAC providesdifferential current output thus supporting single-ended ordifferential applications. Both DACs are simultaneously updatedand provide a nominal full-scale current of 10 mA. Also,the full-scale currents between each DAC are matched to within0.07 dB (i.e., 0.75%), thus eliminating the need for additionalgain calibration circuitry.The AD9761 is manufactured on an advanced low cost CMOSprocess. It operates from a single supply of 2.7 V to 5.5 V andconsumes 200 mW of power. To make the AD9761 complete italso offers an internal 1.20 V temperature-compensated bandgapreference.PRODUCT HIGHLIGHTS Dual 10-Bit, 40 MSPS DACs A pair of high performance 40 MSPS DACs optimized for low distortion performance provide for flexible transmission of I and Q information. 2x Digital Interpolation Filters Dual matching FIR interpolation filters with 62.5 dB stopband rejection precede each DAC input, thus reducing the DACs? reconstruction filter requirements.

The ADL5303 is a monolithic logarithmic detector optimized for the measurement of low frequency signal power in fiberoptic systems and offers a large dynamic range in a versatile andeasily used form. Wide measurement range and accuracy are achieved using proprietary design and precise laser trimming.The ADL5303 requires only a single positive supply, VPS, of 5 V. When using low supply voltages, the log slope can be altered tofit the available span. Low quiescent current and chip disablefacilitate use in battery-operated applications.The input current, IPD, flows in the collector of an optimally scaled NPN transistor, connected in a feedback path around alow offset JFET amplifier. The current summing input nodeoperates at a constant voltage, independent of current, with a default value of 0.5 V; this may be adjusted over a wide range. An adaptive biasing scheme is provided for reducing photo-diode dark current at very low light input levels. The VPDB pin applies approximately 0.1 V reverse bias across the photodiode for IPD = 100 pA, rising linearly to 2.0 V of reverse bias at IPD = 10 mA to improve response time at higher power levels. The input pin INPT is flanked by the VSUM guard pins that track the voltage at the summing node. Connecting the exposed pad of the device to the VSUM pins provides a continuous guard to minimize leakage into the INPT pin.The default value of the logarithmic slope at the VLOG output is set by an internal 5 k? resistor. Logarithmic slope can belowered with an external shunt resistor or increased using the buffer and a pair of external feedback resistors. The addition of a capacitor at the VLOG pin provides a simple low-pass filter.The intermediate voltage, VLOG, is buffered in an output stage that can swing to within about 100 mV of ground and the positive supply, VPS, and provides a peak current drive capacity of ?20 mA. An on-board 2 V reference is provided to facilitate the repositioning of the intercept. The incremental bandwidth of a translinear logarithmic amplifier inherently diminishes for small input currents.

Dual-supply operation extends the specified input current range to 10 mA.The ADL5304 accepts two current inputs to the logarithmic argument. The numerator input, INUM, flows in the collector of an NPN transistor, connected in a feedback path around a low offset JFET amplifier. The denominator current, IDEN, is treated in the same way, which allows for log ratio operation. The input summing nodes (INUM and IDEN) operate at a constant default voltage of 1.5 V. The VSM1 to VSM4 pins flank the INUM and IDEN inputs to provide a guard voltage to minimize leakage currents.Adaptive photodiode biasing is provided for optical measurements. A monitor current 1.1 times INUM is output at the IMON pin, and an external resistor, RMNTR, at 10 times the photodiode series resistance (RS) applies a voltage across the photodiode that 1st order keeps the internal PD junction at 0 V to minimize dark current.The VLOG output is buffered and can be rescaled through internal gain setting resistors. The internal ILOG varies from ?400 ?A to +400 ?A as INUM changes over 10 decades from 1 pA to 10 mA. This corresponds to 0.5 V to 2.5 V at the VLOG pin in the default configuration shown in Figure 1.Accurate 1.5 V (Pin 1P5V) and 2.0 V (Pin 2VLT) reference outputs allow precise repositioning of the intercept using external resistors.The ADL5304 is available in a 32-lead, 5 mm ? 5 mm LFCSP and specified for operation from ?40?C to +85?C.Applications High accuracy optical power measurement Wide range baseband log compression Versatile detector for high speed APC loops

The ADL5315 is a wide input current range precision high-side current mirror featuring a stable and user-adjustable input voltage. It is optimized for use with PIN photodiodes, but its flexibility and wide operating range make it suitable for a broad array of additional applications. The part provides a compact solution for the common and often challenging problem of interfacing an optical power monitoring device (such as a log amp) to the cathode-side of a PIN photodiode. The ADL5315 mirrors the current at the cathode at a 1:1 ratio over a six-decade range, producing an output exactly proportional to the reference current monitored. Competing optical current monitors have much higher mirror ratios over narrower dynamic ranges, rendering proportional outputs at very low input currents impossible, while discrete solutions are more tedious to implement and may require significantly more board space.
