16-bit DAC sees a good fit for optical networking

Sunnyvale, CA — Four 32-channel, 16-bit digital-to-analog converts (DACs) have been developed for optical networking designs that are delivered in an 8 x 8-mm, 56-lead QFN.

The MAX5732, MAX5733, MAX5734, and MAX5735 deliver a maximum integral non-linearity of 0.024 percent FSR and a differential non-linearity of less than 1 LSB. They each offer four output voltage ranges: 0 to +5 V, 0 to +10 V, -2.5 to +7.5 V, and +/-5 V. They also offer a three-wire serial interface for linking up with microprocessors and DSPs.

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 output voltages to be referenced to a remote ground.

A 33MHz SPI-/QSPI-/MICROWIRE- and DSP-compatible serial interface controls 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 provide buffered outputs that can drive 10k 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.
