General Description

The MAX1177 is a 16-bit, low-power, successive approximation analog-to-digital converter (ADC) featuring automatic power-down, a factory-trimmed internal clock, and a byte-wide parallel interface. The device operates from a single +4.75V to +5.25V analog supply and features a separate digital supply input for direct interface with +2.7V to +5.25V digital logic.
