    Description

    The MAX5753/MAX5754/MAX5755 are 32-channel, 14- bit, voltage-output, digital-to-analog converters (DACs). All devices accept a 3V external reference input. The devices include an internal offset DAC that allows all the outputs to be offset and a ground-sensing function, allowing output voltages to be referenced to a remote ground.

    A 33MHz SPI™-/QSPI™-/MICROWIRE™- and digital signal processor (DSP)-compatible serial interface controls the MAX5753/MAX5754/MAX5755. Each DAC has a double-buffered input structure that helps minimize the digital noise feedthrough from the digital inputs to the outputs, and allows for synchronous or asynchronous updating of the outputs. The MAX5753/MAX5754/MAX5755 also provide a DOUT that allows for read-back or daisy chaining multiple devices. The devices provide separate power inputs for the analog and digital sections and provide separate power inputs for the output buffer amplifiers. The MAX5753/MAX5754/MAX5755 include proprietary deglitch circuits to prevent output glitches at power-up and eliminate the need for power sequencing. The devices provide a software-shutdown mode to allow efficient power management. The MAX5753/MAX5754/MAX5755 consume 50µA of supply current in shutdown.

    The MAX5753/MAX5754/MAX5755 provide buffered outputs that can drive 10kΩ in parallel with 100pF. The MAX5753 has a 0 to +10V range; the MAX5754 has a -2.5V to +7.5V range; the MAX5755 has a -5V to +5V range. The MAX5753/MAX5754/MAX5755 are available in 56-pin, 8mm x 8mm, thin QFN or 64-pin thin QFP packages and operate over the 0°C to +85°C temperature range.
