The AD5680, a member of the nanoDAC family, is a single, 18-bit buffered voltage-out digital-to-analog converter (DAC) that operates from a single 4.5 V to 5.5 V supply and is 18-bit monotonic.The AD5680 requires an external reference voltage to set the output range of the DAC. The part incorporates a power-on reset circuit that ensures the DAC output powers up to 0 V (AD5680-1) or to midscale (AD5680-2) and remains there until a valid write takes place.The low power consumption of this part in normal operation makes it ideally suited to portable battery-operated equipment. The power consumption is 1.6 mW at 5 V.The AD5680 on-chip precision output amplifier allows rail-to-rail output swing to be achieved. For remote sensing applications, the output amplifier?s inverting input is available to the user.The AD5680 uses a versatile 3-wire serial interface that operates at clock rates up to 30 MHz, and is compatible with standard SPI?, QSPI?, MICROWIRE?, and DSP interface standards.Applications Closed-loop process control Low bandwidth data acquisition systems Portable battery-powered instruments Gain and offset adjustment Precision setpoint control

The ADMV1013 is a wideband, microwave upconverter optimized for point to point microwave radio designs operating in the 24 GHz to 44 GHz radio frequency (RF) range.The upconverter offers two modes of frequency translation. The device is capable of direct conversion to RF from baseband in-phase quadrature (I/Q) input signals, as well as single-sideband (SSB) upconversion from complex intermediate frequency (IF) inputs. The baseband I/Q input path can be disabled and modulated complex IF signals, anywhere from 0.8 GHz to 6.0 GHz, can be inserted in the IF path and upconverted to 24 GHz to 44 GHz while suppressing the unwanted sideband by typically better than 26 dBc. The serial port interface (SPI) allows adjustment of the quadrature phase and mixer gate voltage to allow optimum sideband suppression and local oscillator (LO) nulling. In addition, the SPI interface allows powering down the output envelope detector to reduce power consumption.The ADMV1013 upconverter comes in a 40-terminal land grid array package (LGA) package. The ADMV1013 operates over the ?40?C to +85?C case temperature range.Applications Point to point microwave radios Radar, electronic warfare systems Instrumentation, automatic test equipment (ATE)

Demonstration circuit 1340 is a triple output regulator consisting of three constant-frequency step-down converters integrated into LTC3569. DC1340 has an input voltage range of 2.5V to 5.5V, with regulators capable of delivering 1.2A or 600mA of load current on corresponding output. The three regulators operate independently with individual Enable pins and enter pulse skipping or burst mode at low loads for increasing efficiency. The DC1340 is a very efficient circuit with efficiency reading above 90%. High operating frequency of 2.25MHz allows exclusive use of the small size, low profile surface mount components. These features plus internal compensation circuits and extremely low quiescent current make the DC1340 demo board an ideal circuit for use in battery-powered, hand-held applications.

The UCC28600 Quasi-Resonant Green-Mode Controller provides engineers with a cost-effective solution for designing energy efficient power supplies. Despite the 8-pin package the device has many built-in advanced protection features. Because most of the pins on the device have dual functions careful attention must be given to the design and layout of the circuit. What follows is a brief discuss
