AD574 DATASHEET PDF

The ADA is a complete bit successive-approximation analog-to-digital converter with 3-state output buffer circuitry for direct interface to an 8- or 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. Offset, linearity and scaling errors are mini- mized by active laser-trimming of thin-film resistors at the wafer stage. The voltage reference uses an implanted buried Zener for low noise and low drift.

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 voltage reference uses an implanted buried Zener for low noise and low drift. On the digital side, I the successive-approximation register, control circuitry and 3-state output buffers. The ADA is available in six different grades. All grades are available in a pin hermetically-sealed ceramic DIP. Patent Nos.
