The MAX167 are complete CMOS sampling 12-bit analog-to-digital converters (ADCs) that combine 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 A/Ds differ only in their analog input range. The MAX167"s input range is -2.5V to +2.5V. 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 MAX167 employ a standard micro-processor 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.
