MAX5735

19-3148; Rev 4; 12/04 KIT ATION EVALU LE B A IL A AV 32-Channel, 16-Bit, Voltage-Output DACs with Serial Interface General Description Features ♦ Guaranteed Monotonic to 16 Bits ♦ 32 Individual DACs in an 8mm x 8mm, 56-Pin, Thin QFN Package ♦ Four Output Voltage Ranges 0 to +5V 0 to +10V -2.5V to +7.5V -5V to +5V ♦ Buffered Voltage Outputs Capable of Driving 10kΩ || 100pF ♦ Glitch-Free Power-Up ♦ SPI-/QSPI-/MICROWIRE-/DSP-Compatible 33MHz Serial Interface MAX5732–MAX5735 The MAX5732–MAX5735 are 32-channel, 16-bit, voltageoutput, 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 MAX5732–MAX5735. Each DAC has a doublebuffered 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 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 MAX5732–MAX5735 include proprietary deglitch circuits to prevent output glitches at power-up and eliminate the need...
