MAX5732MAX5735 19-3148 Rev 7 11/05 32-Channel, 16-Bit, Voltage-Output DACs with Serial Interface General Description Features Guaranteed Monotonic to 16 Bits The MAX5732MAX5735 are 32-channel, 16-bit, voltage- output, digital-to-analog converters (DACs). All devices 32 Individual DACs in an 8mm x 8mm, 56-Pin, accept a 3V external reference input. The devices Thin QFN Package or 64-Pin TQFP Package include an internal offset DAC that allows all the outputs Four Output Voltage Ranges to be offset and a ground-sensing function, allowing out- 0 to +5V (MAX5732) put voltages to be referenced to a remote ground. 0 to +10V (MAX5733) -2.5V to +7.5V (MAX5734) A 33MHz SPI-/QSPI-/MICROWIRE- and digital -5V to +5V (MAX5735) signal processor (DSP)-compatible serial interface con- trols the MAX5732MAX5735. Each DAC has a double- Buffered Voltage Outputs Capable of Driving buffered input structure that helps minimize the digital 10k 100pF noise feedthrough from the digital inputs to the outputs, Glitch-Free Power-Up and allows for synchronous or asynchronous updating SPI-/QSPI-/MICROWIRE-/DSP-Compatible 33MHz of the outputs. The MAX5732MAX5735 also provide a Serial Interface DOUT that allows for read-back or daisy chaining multi- ple devices. The devices provide separate power inputs for the analog and digital sections and provide Ordering Information separate power inputs for the output buffer amplifiers. OUTPUT MAX The MAX5732MAX5735 include proprietary deglitch PIN- PKG PART VOLTAGE INL circuits to prevent output glitches at power-up and PACKAGE CODE (V) (LSB) eliminate the need for power sequencing. The devices provide a software-shutdown mode to allow efficient 56 Thin MAX5732AUTN 0 to +5 8 T5688-3 power management.
