Product Summary
The AD574AKD is a complete 12-bit successive-approximation analog-to-digital converter with 3-state output buffer circuitry for direct interface to an 8- or 16-bit microprocessor bus. A high precision voltage reference and clock are included on-chip, and the circuit guarantees full-rated performance without external circuitry or clock signals. The AD574AKD is available in six different grades. The AD574AKD is specified for operation over the 0 to +70℃ temperature range. The AD574AS, T, and U are specified for the –55 to +125℃ range. All grades are available in a 28-pin hermetically-sealed ceramic DIP. Also, the J, K, and L grades are available in a 28-pin plastic DIP and PLCC, and the J and K grades are available in ceramic LCC.
