Complete 5µs, CMOS 10-Bit A/D Converter

The MAX173 is a complete, 10-bit linear analog-to­digital converter (ADC) that combines high speed, low power consumption, and an on-chip voltage reference. The conversion time is 5µs. The buried zener reference provides low drift and low noise performance.

External component requirements are limited to only decoupling capacitors for the power supply and refer­ence voltages. On-chip clock circuitry is also included which can either be driven from an external source, or in stand-alone applications, from a crystal.

The MAX173 uses a standard microprocessor interface architecture. Three-state data outputs are controlled by Read (RD) and Chip Select (CS) inputs. Data access and bus release times of 90ns and 75ns respectively ensure compatibility with most popular microproces­sors without resorting to wait states.
