GENERAL DESCRIPTION

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.
