Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

The MAX1157/MAX1159/MAX1175 14-bit, low-power, successive-approximation analog-to-digital converters (ADCs) feature automatic power-down, a factory-trimmed internal clock, and a 14-bit wide parallel interface. The devices operate from a single +4.75V to +5.25V analog supply and feature a separate digital supply input for direct interface with +2.7V to +5.25V digital logic.

The MAX1157 accepts an analog input voltage range from 0 to +10V while the MAX1159 accepts a bipolar analog input voltage range of ±10V. The MAX1175 accepts a bipolar analog input voltage range of ±5 V. All devices consume only 23mW at a sampling rate  of 135ksps when using an external reference and 29mW when using the internal +4.096V reference. AutoShutdown™ reduces supply current to 0.4mA at 10ksps. The MAX1157/MAX1159/MAX1175 are ideal for high-performance, battery-powered data-acquisition applications. Excellent AC performance (THD = -100dB) and DC accuracy (±1LSB INL) make the MAX1157/ MAX1159/MAX1175 ideal for industrial process control, instrumentation, and medical applications.

The MAX1157/MAX1159/MAX1175 are available in a 28-pin TSSOP package and are fully specified over the -40°C to +85°C extended temperature range and the 0°C to +70°C commercial temperature range.
