General Description
The MAX172 is a complete 12-Bit analog-to-digital
converter (ADC) that combines high speed, low power
consumption, and an on-chip voltage reference. The
conversion time is 10ps. 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 refer-
ence voltages. On-chip clock circuitry is also included
which can either be driven from an external source,
or in stand-alone applications, can be used with a
crystal.
The MAX172 uses a standard microprocessor interface
architecture-Three-state data outpgtti are controlled
by Read (RD) and Chip Select (CS) inputs. Data
access and bus release times of 90 and 75ns respec-
tively ensure compatibility with most popular micro-
processors without resorting to wait states.
