AD7813 Datasheet +2.7 V to +5.5 V 400 kSPS 8-/10-Bit Sampling ADC

Manufacturer: Analog Devices

General Description

PRODUCT HIGHLIGHTS The AD7813 is a high-speed, microprocessor-compatible, 8-/10-bit analog-to-digital converter with a maximum throughput of 400 kSPS.

The converter operates off a single +2.7 V to +5.5 V supply and contains a 2.3 µs successive approximation A/D converter, track/hold circuitry, on-chip clock oscillator and 8-bit wide parallel interface.

The parallel interface is designed to allow easy interfacing to microprocessors and DSPs.
