The AD585 is a complete monolithic sample-and-hold circuit consisting of a high performance operational amplifier in series with an ultralow leakage analog switch and a FET input integrating amplifier. An internal holding capacitor and matched applications resistors have been provided for high precision and applications flexibility.The performance of the AD585 makes it ideal for high speed 10- and 12-bit data acquisition systems, where fast acquisition time, low sample-to-hold offset, and low droop are critical. The AD585 can acquire a signal to ±0.01% in 3 µs maximum, and then hold that signal with a maximum sample-to-hold offset of 3 mV and less than 1 mV/ms droop, using the on-chip hold capacitor. If lower droop is required, it is possible to add a larger external hold capacitor.The high speed analog switch used in the AD585 exhibits aperture jitter of 0.5 ns, enabling the device to sample full scale (20 V peak-to-peak) signals at frequencies up to 78 kHz with 12-bit precision.The AD585 can be used with any user-defined feedback net-work to provide any desired gain in the sample mode. On-chip precision thin-film resistors can be used to provide gains of +1, -1, or +2. Output impedance in the hold mode is sufficiently low to maintain an accurate output signal even when driving the dynamic load presented by a successive-approximation A/D converter. However, the output is protected against damage from accidental short circuits.The control signal for the HOLD command can be either active high or active low. The differential HOLD signal is compatible with all logic families, if a suitable reference level is provided. An on-chip TTL reference level is provided for TTL compatibility.The AD585 is available in three performance grades. The JP grade is specified for the 0°C to +70°C commercial temperature range and packaged in a 20-pin PLCC. The AQ grade is specified for the -25°C to +85°C industrial temperature range and is packaged in a 14-pin cerdip. The SQ and SE grades are specified for the -55°C to +125°C military temperature range and are packaged in a 14-pin cerdip and 20-pin LCC.

The AD7716 is a signal processing block for data acquisition systems. It is capable of processing four channels with bandwidths of up to 584 Hz. Resolution is 22 bits and the usable dynamic range varies from 111 dB with an input bandwidth of 36.5 Hz to 99 dB with an input bandwidth of 584 Hz.The device consists of four separate A/D converter channels that are implemented using sigma-delta technology.

This allows a data acquisition system with up to 32 channels to be set up in a simple fashion. The output word from the device contains 32 bits of data. One bit is determined by the state of the DIN1 input and may be used, for example, in an ECG system with an external pacemaker detect circuit to indicate that the output word is invalid because of the presence of a pacemaker pulse.

The AD9708 is the 8-bit resolution member of the TxDAC™ series of high performance, low power CMOS digital-to-analog converters (DACs). The TxDAC™ family, which consists of pin compatible 8-, 10-, 12-, and 14-bit DACs, was specifically optimized for the transmit signal path of communication systems. All of the devices share the same interface options, small outline package and pinout, thus providing an upward or downward component selection path based on performance, resolution and cost. The AD9708 offers exceptional ac and dc performance while supporting update rates up to 125 MSPS.The AD9708's flexible single-supply operating range of 2.7 V to 5.5 V and low power dissipation are well suited for portable and low power applications. Its power dissipation can be further reduced to 45 mW, without a significant degradation in performance, by lowering the full-scale current output. In addition, a power-down mode reduces the standby power dissipation to approximately 20 mW.The AD9708 is manufactured on an advanced CMOS process. A segmented current source architecture is combined with a proprietary switching technique to reduce spurious components and enhance dynamic performance. Edge-triggered input latches and a temperature compensated bandgap reference have been integrated to provide a complete monolithic DAC solution.

The AD9708 can be driven by a variety of external reference voltages. The AD9708's full-scale current can be adjusted over a 2 mA to 20 mA range without any degradation in dynamic performance. Thus, the AD9708 may operate at reduced power levels or be adjusted over a 20 dB range to provide additional gain ranging capabilities.The AD9708 is available in a 28-pin SOIC package. It is specified for operation over the industrial temperature range.
