Description

The MAX5158/MAX5159 low-power, serial, voltage-output, dual, 10-bit digital-to-analog converters (DACs) consume only 500µA from a single +5V (MAX5158) or +3V (MAX5159) supply. These devices feature Rail-to-Rail output swing and are available in a space-saving 16-pin QSOP package. To maximize dynamic range, the DAC output amplifiers are configured with an internal gain of +2V/V.

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 a 2µA programmable shutdown, 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. The MAX5158/MAX5159 provide a programmable logic pin for added functionality and a serial-data output pin for daisy chaining.
