Product Details
The AD4030-24/AD4032-24 are 2 MSPS or 500 kSPS successive approximation register (SAR), analog-to-digital converters (ADC) with Easy Drive™. With a guaranteed maximum ±0.9 ppm integral nonlinearity (INL) and no missing codes at 24-bits, the AD4030-24/AD4032-24 achieve unparalleled precision from −40°C to +125°C. Figure 1 shows the functional architecture of the AD4030-24/AD4032-24.
A low drift, internal precision reference buffer eases voltage reference sharing with other system circuitry. The AD4030-24/AD4032-24 offer a typical dynamic range of 109 dB when using a 5 V reference. The low noise floor enables signal chains requiring less gain and lower power. A block averaging filter with programmable decimation ratio can increase dynamic range up to 155.5 dB. 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/AD4032-24. Both single-ended and differential signals are supported.
The versatile Flexi-SPI serial peripheral interface (SPI) eases host processor and ADC integration. A wide data clocking window, multiple SDO lanes, and optional dual data rate (DDR) data clocking can reduce the serial clock to 10 MHz while operating at a sample rate of 2 MSPS or 500 kSPS. Echo clock mode and ADC host clock mode relax the timing requirements and simplify the use of digital isolators.
The 7 mm × 7 mm, 64-Ball CSP_BGA package of the AD4030-24/AD4032-24 integrates all critical power supply and reference bypass capacitors, reducing the footprint and system component count, and lessening sensitivity to board layout.

Precision ADC Driver Tool
The Precision ADC Driver Tool is a web application that simulates the performance of precision ADC and driver combinations. Potential issues with driver selection, kickback settling, and distortion are flagged, and design tradeoffs can be quickly evaluated. Simulations and calculations include system noise, distortion, and settling of the ADC input
