AD4630-16BBCZ is a 2-channel, simultaneous sampling, Easy Drive�, successive approximation register (SAR), analogue-to-digital converter (ADC). A low-drift, internal precision-reference buffer eases voltage-reference sharing with other system circuitry. It offers a typical dynamic range of 97.4dB when using a 5V reference. The low-noise floor enables signal chains to utilize less gain and lower power. A block-averaging filter with a programmable decimation ratio is available and can reduce noise for low-bandwidth signals, improving accuracy. The wide differential input and common-mode ranges allow inputs to use the full voltage reference (±VREF) range without saturating, simplifying signal-conditioning requirements and system calibration. Applications include automatic test equipment, digital control loops, medical instrumentation, seismology, semiconductor manufacturing, and scientific instrumentation.
