AD4695BCPZ

AD4695 is a compact, high accuracy, low power, 16-channel, 16bit multiplexed input precision, successive approximation register (SAR) analogue-to-digital converter (ADC) with Easy Drive features and extensive digital functionality. It is optimal for use in space constrained, multichannel, precision data acquisition systems and monitoring circuits. The AD4695 feature a true 16-bit SAR ADC core with no missing codes, a 16-channel, low crosstalk multiplexer, a flexible channel sequencer, overvoltage protection clamp circuits on each analogue input, on-chip oversampling and decimation, threshold detection and alert indicators and an autonomous conversion (autocycle) mode. Typical applications include photodiode monitoring, medical instrumentation, vital signs monitoring, electronic test and measurement, automated test equipment, instrumentation and process control and battery-powered equipment.
