AD7813YR

The AD7813YR 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 s 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. The 10-bit conversion result is read by carrying out two 8-bit read operations.
