The AD574AJNZ is a complete 12-bit successive-approximation Analog-to-digital Converter (ADC) with 3-state output buffer circuitry for direct interface to a 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. Offset, linearity and scaling errors are minimized 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. On the digital side, I2L logic is used for the successive-approximation register, control circuitry and 3-state output buffers.

• Guaranteed linearity over temperature
• No missing codes over temperature
• 35μs Maximum conversion time
• Buried zener reference
