The MAX177 is a complete CMOS sampling 10-bit analog-to-digital converter (ADC) that combines an on-chip track-and-hold and voltage reference along with high conversion speed and low power consumption. A conversion time of 8.33,us includes settling time for the track-and-hold. An internal buried zener reference provides low drift with low noise. The MAX177 accepts -2.5V to +2.5V inputs. External components are limited to only decoupling capacitors for the power supply and reference voltages. On-chip clock circuitry can either be driven from an external clock source or a crystal. The MAX177 employs a standard microprocessor interface. Three-state data outputs can be configured for 8- or 12-bit data buses. Data access and bus release timing specs are compatible with most popular microprocessors without resorting to wait states.
