The AD4630-16 is a two-channel, simultaneous sampling, Easy Drive?, 2 MSPS successive approximation register (SAR) analog-to-digital converter (ADC). With a guaranteed maximum ?3 ppm integral nonlinearity (INL) and no missing codes at 16-bits, the AD4630-16 achieves excellent precision from ?40?C to +125?C. Figure 1 in the data sheet shows the functional architecture of the AD4630-16.A low-drift, internal precision reference buffer eases voltage reference sharing with other system circuitry. The AD4630-16 offers a typical dynamic range of 97.4 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 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 (?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 AD4630-16. 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 integrates all critical power supply and reference bypass capacitors, reducing the footprint and system component count, and lessening sensitivity to board layout.APPLICATIONS Automatic test equipment Digital control loops Medical instrumentation Seismology Semiconductor manufacturing Scientific instrumentation

The AD5560 is a high performance, highly integrated device power supply consisting of programmable force voltages and measure ranges. This part includes the required DAC levels to set the programmable inputs for the drive amplifier, as well as clamping and comparator circuitry.
