AD4030-24BBCZ

AD4030-24BBCZ is a 2MSPS successive approximation register (SAR), analogue-to-digital converter (ADC) with Easy Drive™. A low drift, internal precision reference buffer eases voltage reference sharing with other system circuitry. It offers a typical dynamic range of 109dB when using a 5V reference. The low-noise floor enables signal chains requiring less gain and lower power. A block averaging filter with a programmable decimation ratio can increase dynamic range upto 155.5dB. The wide differential input and common mode ranges allow inputs to use the full ±VREF range without saturating, simplifying signal conditioning requirements and system calibration. The improved settling of the easy drive analogue inputs broadens the selection of analogue front-end components compatible with the device. It is used in applications such as automatic test equipment, digital control loops, medical instrumentation, seismology, semiconductor manufacturing, and scientific instrumentation.
