MAX5156 - Low-Power / Dual / 12-Bit Voltage-Output DACs

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-toRail® output swing and are available in space-saving 16-pin QSOP and DIP packages.

Key Features

  • include a programmable shutdown (2µA), hardware-shutdown lockout, a separate voltage reference for each DAC, power-on reset, and an activelow clear input (CL) that resets all registers and DACs to zero. The MAX5156/MAX5157 provide a programmable logic output pin for added functionality, and a serialdata output pin for daisy chaining. ____________________________Features o 12-Bit Dual DAC with Configurable Output Amplifier o Single-Supply Operation: +5V (MAX5156) +3V (MAX5157) o Rail-to-Rail Out.

19-1317; Rev 1; 12/97 Low-Power, Dual, 12-Bit Voltage-Output DACs with Configurable Outputs _______________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-toRail® 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. The 3-wire serial interface is SPI™/QSPI™ and Microwire™ compatible.
