MAX531 - +5V / Low-Power / Voltage-Output / Serial 12-Bit DACs

Description

The MAX531/MAX538/MAX539 are low-power, voltageoutput, 12-bit digital-to-analog converters (DACs) specified for single +5V power-supply operation.

The MAX531 can also be operated with ±5V supplies.

The MAX538/MAX539 draw only 140µA, and the MAX531 (with internal reference) draws only 260µA.

Features

  • o Operate from Single +5V Supply o Buffered Voltage Output o Internal 2.048V Reference (MAX531) o 140µA Supply Current (MAX538/MAX539) o INL = ±1/2LSB (max) o Guaranteed Monotonic over Temperature o Flexible Output Ranges: 0V to VDD (MAX531/MAX539) VSS to VDD (MAX531) 0V to 2.6V (MAX531/MAX538) o 8-Pin SO/DIP (MAX538/MAX539) o Power-On Reset o Serial Data Output for Daisy-Chaining MAX531/MAX538/MAX539 _______________________.

19-0172; Rev 6; 2/97 +5V, Low-Power, Voltage-Output, Serial 12-Bit DACs _______________General Description The MAX531/MAX538/MAX539 are low-power, voltageoutput, 12-bit digital-to-analog converters (DACs) specified for single +5V power-supply operation. The MAX531 can also be operated with ±5V supplies. The MAX538/MAX539 draw only 140µA, and the MAX531 (with internal reference) draws only 260µA. The MAX538/MAX539 come in 8-pin DIP and SO packages, while the MAX531 comes in 14-pin DIP and SO packages. All parts have been trimmed for offset voltage, gain, and linearity, so no further adjustment is necessary. The MAX538’s buffer is fixed at a gain of +1 and the MAX539’s buffer at a gain of +2.
