AD4030-24 24-Bit, 2MSPS, SAR ADCs

Analog Devices Inc. AD4030-24 24-Bit, 2MSPS, SAR ADCs feature a guaranteed maximum ±0.9ppm integral nonlinearity (INL) and no missing codes at 24-bits resulting in unparalleled precision from -40°C to +125°C. The successive approximation register (SAR) analog-to-digital converter (ADC) with Easy Drive™ has a low-drift, internal precision reference buffer easing voltage reference sharing with other system circuitry. The AD4030-24 delivers a typical dynamic range of 109dB when using a 5V reference. The low noise floor enables signal chains to require less gain and lower power. The low noise floor allows signal chains to require less gain and lower power. The dynamic range on the device can be increased up to 155.5dB with a block averaging filter with a programmable decimation ratio. 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 analog inputs broadens the selection of analog front-end components compatible with the AD4030-24. Both single-ended and differential signals are supported.
