MAX1065/MAX1066 19-2466 Rev 1 6/09 Low-Power, 14-Bit Analog-to-Digital Converters with Parallel Interface General Description Features The MAX1065/MAX1066 14-bit, low-power successive 14-Bit-Wide (MAX1065) and Byte-Wide (MAX1066) approximation analog-to-digital converters (ADCs) fea- Parallel Interface ture automatic power-down, a factory-trimmed internal High Speed: 165ksps Sample Rate clock, and a high-speed, 14-bit-wide (MAX1065) or byte-wide (MAX1066) parallel interface. The devices Accurate: 1LSB DNL (max), 1LSB INL (max) operate from a single 4.75V to 5.25V analog supply and 4.096V, 35ppm/C Internal Reference a 2.7V to 5.25V digital supply. The MAX1065/MAX1066 use an internal 4.096V refer- External Reference Range 3.8V to 5.25V ence or an external reference. The MAX1065/MAX1066 Single 4.75V to 5.25V Analog Supply Voltage consume only 1.8mA at a sampling rate of 165ksps with external reference and 2.7mA with internal reference. 2.7V to 5.25V Digital Supply Voltage AutoShutdown reduces supply current to 0.1mA at Low Supply Current 10ksps. 1.8mA (External Reference) The MAX1065/MAX1066 are ideal for high-performance, 2.7mA (Internal Reference) battery-powered, data-acquisition applications. 0.1mA AutoShutdown Mode (10ksps, External Excellent dynamic performance and low-power con- Reference) sumption in a small package make the MAX1065/ Small Footprint MAX1066 the best choice for circuits with demanding 28-Pin TSSOP Package (14-Bit Wide) power consumption and space requirements. 20-Pin TSSOP Package (Byte Wide) 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 0C to +70C commercial, or the -40C to +85C extended temperature range.
