The MAX163, MAX164, and 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 8.33μs includes settling time for the track-and-hold. An internal buried zener reference provides low drift with low noise.
The three A/Ds differ only in their analog input range. The MAX163 accepts 0V to +SV inputs, the MAX164 accepts -SV to +SV inputs, and the MAX167's input range is -2.SV to +2.SV. 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 MAX163/164/167 employ 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.
