MAX5732的产品描述：
The MAX5732–MAX5735 are 32-channel, 16-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 out-put voltages to be referenced to a remote ground.
A 33MHz SPI™-/QSPI™-/MICROWIRE™- and digital signal processor (DSP)-compatible serial interface con-trols the MAX5732–MAX5735. 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 MAX5732–MAX5735 also provide a DOUT that allows for read-back or daisy chaining multi-ple devices. The devices provide separate powerinputs for the analog and digital sections and provide separate power inputs for the output buffer amplifiers.The MAX5732–MAX5735 include proprietary deglitch circuits to prevent output glitches at power-up and eliminate the need for power sequencing. The evices provide a software-shutdown mode to allow efficient power management. The MAX5732–MAX5735 con- sume 50µA of supply current in shutdown.
The MAX5732–MAX5735 provide buffered outputs that can drive 10kΩ in parallel with 100pF. The MAX5732 has a 0 to +5V output range; the MAX5733 has a 0 to +10V range; the MAX5734 has a -2.5V to +7.5V range; the MAX5735 has a -5V to +5V range. The MAX5732– MAX5735 are available in a 56-pin, 8mm x 8mm, thin QFN package in both the commercial (0°C to +70°C) and extended (-40°C to +85°C) temperature ranges.
