The MAX1065/MAX1066 14-bit, low-power successive approximation analog-to-digital converters (ADCs) feature automatic power-down, a factory-trimmed internal clock, and a high-speed, 14-bit-wide (MAX1065) or byte-wide (MAX1066) 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 MAX1065/MAX1066 use an internal 4.096V reference or an external reference. The MAX1065/MAX1066 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 MAX1065/MAX1066 are ideal for high-performance, battery-powered, data-acquisition applications. Excellent dynamic performance and low-power consumption in a small package make the MAX1065/ MAX1066 the best choice for circuits with demanding power consumption and space requirements. The 14-bit-wide MAX1065 is available in a 28-pin TSSOP package, and the byte-wide MAX1066 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.
