AD7686*

The AD7686 is a 16-bit, 550 kSPS, charge redistribution successive-approximation, Analog-to-Digital Converter which operates from a single power supply. It contains a high-speed 16-Bit sampling ADC without any missing code, an internal conversion clock, error correction circuits, and a flexible serial interface port. The part also contain a low noise, wide bandwidth, very short aperture delay track/hold circuit which can sample an analog input range from 0V to REF. The reference voltage REF is applied externally and can be set up to the supply voltage. It features a very high sampling rate mode (Warp) and, for asynchronous conversion rate applications, a fast mode (Normal) and, for low power applications, a reduced power mode (Impulse) where the power is scaled with the throughput.

The serial interface features the possibility to "Daisy chain" several ADCs on a single 3 wires bus and provides an optionnal Busy indicator.

The AD7686 is hardware factory calibrated. It is fabricated using CMOS process and is housed in 10-lead
SOIC package with operation specified from 40°C to +85°C.
