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 || 100p F - Glitch-Free Power-Up - SPI-/QSPI-/MICROWIRE-/DSP-patible 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)-patible 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 for power sequencing. The devices provide a software-shutdown mode to allow efficient power management. The MAX5732- MAX5735 consume 50µA of supply current in shutdown. The MAX5732- MAX5735 provide buffered outputs that can drive 10kΩ in parallel with 100p F. 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...
