Low-Power, Dual, 13-Bit Voltage-Output DACs with Serial Interface

Dual, Serial, Voltage-Output DAC in a QSOP Package

Please check latest availability status for a specific part variant.


The MAX5150/MAX5151 low-power, serial, voltage-output, dual 13-bit digital-to-analog converters (DACs) consume only 500µA from a single +5V (MAX5150) or +3V (MAX5151) supply. These devices feature Rail-to-Rail output swing and are available in a space-saving 16-pin QSOP package. To maximize the dynamic range, the DAC output amplifiers are configured with an internal gain of +2.

The 3-wire serial interface is SPI™/QSPI™ and MICROWIRE™ compatible. Each DAC has a double-buffered input organized as an input register followed by a DAC register, which allows the input and DAC registers to be updated independently or simultaneously with a 16-bit serial word. Additional features include programmable shutdown (2µA), hardware-shutdown lockout, a separate reference voltage input for each DAC that accepts AC and DC signals, and an active-low clear input (CL) that resets all registers and DACs to zero. These devices provide a programmable logic pin for added functionality, and a serial-data output pin for daisy-chaining.
