Low-Power, 16-Bit Analog-to-Digital Converters with Parallel Interface

The MAX1165/MAX1166 16-bit, low-power, successive-approximation analog-to-digital converters (ADCs) feature automatic power-down, factory-trimmed internal clock, and a 16-bit wide (MAX1165) or byte wide (MAX1166) parallel interface. The devices operate from a single +4.75V to +5.25V analog supply and a +2.7V to +5.25V digital supply.

The MAX1165/MAX1166 use an internal 4.096V reference or an external reference. The MAX1165/MAX1166 consume only 1.8mA at a sampling rate of 165ksps with external reference and 2.7mA with internal reference. AutoShutdown™ reduces supply current to 0.1mA at 10ksps.

The MAX1165/MAX1166 are ideal for high-performance, battery-powered, data-acquisition applications. Excellent dynamic performance and low power consumption in a small package make the MAX1165/MAX1166 ideal for circuits with demanding power consumption and space requirements.

The 16-bit wide MAX1165 is available in a 28-pin TSSOP package and the byte wide MAX1166 is available in a 20-pin TSSOP package. Both devices are available in either the 0°C to +70°C commercial, or the -40°C to +85°C extended temperature range.
