The MAX1065/MAX1066 are 14-bit, low-power successive approximation analog-to-digital converters (ADCs) that 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.
The MAX1065 and MAX1066 are low‑power, 14‑bit successive‑approximation ADCs that operate from a single 4.75 V to 5.25 V analog supply and a 2.7 V to 5.25 V digital supply. They feature automatic power‑down, an internal 4.096 V reference (or external reference), and a high‑speed parallel data bus.
The MAX1065 is offered in a 28‑pin TSSOP package, while the MAX1066 uses a 20‑pin TSSOP. Both devices are available in a commercial temperature range of 0 °C to 70 °C and an extended range of –40 °C to 85 °C. Typical applications include data‑acquisition, industrial process measurements, and battery‑powered systems.
