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.

The MAX1177 accepts an analog input voltage range from 0 to +10V. It consumes no more than 26.5mW at a sampling rate of 135ksps when using an external reference, and 31mW when using the internal +4.096V reference. AutoShutdown™ reduces supply current to 0.4mA at 10ksps.

The MAX1177 is ideal for high-performance, battery-powered, data-acquisition applications. Excellent AC performance (THD = -100dB) and DC accuracy (±3 LSB INL) make this device ideal for industrial process control, instrumentation, and medical applications.

The MAX1177 is available in a 20-pin TSSOP package and is fully specified over the -40°C to +85°C extended temperature range and the 0°C to +70°C commercial temperature range.
