Low-Power, Dual, 13-Bit Voltage-Output DACs with Serial Interface
_______________General Description
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-toRail® 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 doublebuffered 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.
