General Description

The MAX5156/MAX5157 low-power, serial, voltage-output, dual 12-bit digital-to-analog converters (DACs)

consume only 500μA from a single +5V (MAX5156) or +3V (MAX5157) supply. These devices feature Rail-to

Rail?output swing and are available in space-saving 16-pin QSOP and DIP packages. Access to the inverting input allows for specific gain configurations, remote sensing, and high output current capability, making these devices ideally suited for industrial process controls. These devices are also well suited for digitally programmable (4–20mA) current loops.
