The MAX5104 is a low-power, serial, voltage-output, dual 12-bit digital-to-analog converter (DAC) that consumes only 500µA from a single +5V supply. This device features Rail-to-Rail® output swing and is 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 +2V/V. The 3-wire serial interface is SPI™/QSPI™/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 power- down (2µA), hardware power-down lockout (PDL), 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.
The MAX5104 is a low‑power, dual‑channel 12‑bit digital‑to‑analog converter that operates from a single +5 V supply and consumes only 500 µA in normal mode. It features rail‑to‑rail output swing, an internal gain of +2 V/V, and a space‑saving 16‑pin QSOP package.
The device uses a 3‑wire serial interface compatible with SPI, QSPI and MICROWIRE, supports independent or simultaneous register updates, and allows daisy‑chaining of multiple DACs. Power‑down mode reduces current to 2 µA while retaining the serial interface for wake‑up and configuration.
