Product Details

The AD4630-16/AD4632-16 are 2-channel, simultaneous sampling, Easy Drive, 2 MSPS or 500 kSPS successive approximation register (SAR), analog-to-digital converters (ADCs). With a guaranteed maximum ±3 ppm integral nonlinearity (INL) and no missing codes at 16-bits, the AD4630-16/AD4632-16 achieve excellent precision from −40°C to +125°C. Figure 1 in the data sheet shows the functional architecture of the AD4630-16/AD4632-16.

A low-drift, internal precision-reference buffer eases voltage-reference sharing with other system circuitry. The AD4630-16/AD4632-16 offer a typical dynamic range of 97.4 dB when using a 5 V reference. The low noise floor enables signal chains utilizing less gain and lower power. A block averaging filter with 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. The improved settling of the Easy Drive analog inputs broadens the selection of analog front end (AFE) components compatible with the AD4630-16/AD4632-16. 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 serial-data output (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. Echo clock mode can relax the timing requirements and simplify the use of digital isolators.

The ball grid array (BGA) package of the AD4630-16/AD4632-16 integrates all critical power supply and reference bypass capacitors, reducing the footprint and system-component count, and lessening sensitivity to board layout.
