Description
PRODUCT HIGHLIGHTS
The AD574A 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 AD574A design is implemented using Analog Devices’ Bipolar/I2L process, and integrates all analog and digital functions on one chip
