The AD5763 is a dual, 16-bit, serial input, bipolar voltage output digital-to-analog converter (DAC) that operates from supply voltages of ±4.75 V up to ±5.25 V. The nominal full-scale output range is ±4.096 V. The AD5763 provides integrated output amplifiers, reference buffers, and proprietary power-up/ power-down control circuitry. The part also features a digital I/O port, which is programmed via the serial interface. The part incorporates digital offset and gain adjust registers per channel.The AD5763 is a high performance converter that offers guar-anteed monotonicity, integral nonlinearity (INL) of ±1 LSB, low noise, and 10 μs settling time. During power-up (when the supply voltages are changing), the outputs are clamped to 0 V via a low impedance path.The AD5763 uses a serial interface that operates at clock rates of up to 30 MHz and is compatible with DSP and microcontroller interface standards. Double buffering allows the simultaneous updating of all DACs. The input coding is programmable to either twos complement or offset binary formats.

The AD7142 and AD7142-1 are integrated capacitance-to-digital converters (CDCs) with on-chip environmental calibration for use in systems requiring a novel user input method. The AD7142 and AD7142-1 can interface to external capacitance sensors implementing functions such as capacitive buttons, scroll bars, or wheels.The CDC has 14 inputs channeled through a switch matrix to a 16-bit, 250 kHz sigma-delta (∑-Δ) capacitance-to-digital converter. The CDC is capable of sensing changes in the capacitance of the external sensors and uses this information to register a sensor activation. The external sensors can be arranged as a series of buttons, as a scroll bar or wheel, or as a combination of sensor types. By programming the registers, the user has full control over the CDC setup. High resolution sensors require minor software to run on the host processor. The AD7142 and AD7142-1 have on-chip calibration logic to account for changes in the ambient environment. The calibration sequence is performed automatically and at continuous intervals, when the sensors are not touched. This ensures that there are no false or nonregistering touches on the external sensors due to a changing environment.The AD7142 has an SPI-compatible serial interface, and the AD7142-1 has an I2C-compatible serial interface. Both parts have an interrupt output, as well as a general-purpose input/ output (GPIO).

The AD7528’s matched CMOS DACs make a whole new range of applications circuits possible, particularly in the audio, graphics and process control areas. Small package size: combining the inputs to the on-chip DAC latches into a common data bus and adding a DAC A/DAC B select line has allowed the AD7528 to be packaged in either a small 20-lead DIP, SOIC or PLCC.APPLICATIONSDigital Control of: Gain/Attenuation Filter Parameters Stereo Audio Circuits X-Y Graphics
