AD4695/96 Analog-to-Digital Converter

ADI's AD4696 is the industry's first 16-channel, 16-bit SAR ADC with a multiplexed front end. With Easy Drive mode applied to every channel, the AD4696 feature set allows for the simplification of signal chains by eliminating the need for certain circuit elements and broadening the direct compatibility of companion components.

The AD4695 and AD4696 are optimal for use in space-constrained multichannel precision data acquisition systems and monitoring circuits. They feature a true 16-bit SAR ADC core with no missing codes; a 16-channel, low crosstalk multiplexer; flexible channel sequencer; overvoltage protection clamp circuits on each analog input; on-chip oversampling and decimation; threshold detection and alert indicators; and an autonomous conversion (autocycle) mode.

The AD4695 and AD4696 are available in a 5 mm x 5 mm 32-lead LFCSP with operation specified from -40°C to +125°C.

The EVAL-AD4696FMCZ allows users to quickly evaluate the performance of the AD4696 with no or minimal hardware modifications. The hardware includes two externally driven analog input channels for evaluating AC performance and 14 channels with DC levels generated onboard for evaluating DC and settling performance. The externally driven channels have configurable drive circuitry and interface with precision signal generators via SMA connectors.

Features

• EasyDrive mode per channel and on the reference input broadens the selection of companion components that are directly compatible with the AD4696
