The MAX5773/MAX5774/MAX5775 32-channel, 14-bit, voltage-output, digital-to-analog converters (DACs) are ideal for applications requiring a high number of programmable voltages. The MAX5773/MAX5774/MAX5775 can be programmed to calibrate the 14-bit input data word for gain and offset errors before updating the DAC output.
An SPI™-/QSPI™-/MICROWIRE™- or DSP-compatible serial interface controls the MAX5773/MAX5774/MAX5775. Each DAC channel has its own input, gain, and offset register. These three registers pass data through one of the two multiplier accumulator units (MACs), resulting in a voltage output corrected for gain and offset error. Each DAC channel has a double-buffered input structure to minimize the digital-noise feedthrough from the digital inputs to the outputs, and allows for synchronous or asynchronous updating of the outputs. The DAC outputs update independently or simultaneously with a single software or hardware command. The MAX5773/MAX5774/MAX5775 also provide a digital output (DOUT) that allows for readback or daisy chaining of multiple devices.
All DAC outputs are buffered and drive 10kΩ in parallel with 100pF. The MAX5773 has a 0 to +10V output range; the MAX5774 has a -2.5V to +7.5V output range; and the MAX5775 has a -5V to +5V output range. The MAX5773/MAX5774/MAX5775 are available in a 68-pin, 10mm x 10mm, TQFN package and a 64-pin, 12mm x 12mm, TQFP package. The MAX5773/MAX5774/MAX5775 are specified over the 0°C to +85°C temperature range. Refer to the MAX5753/MAX5754/MAX5755 data sheet for similar 14-bit, 32-channel DACs without offset and gain calibration.

Product Detail
The MAX5774 evaluation kit (EV kit) demonstrates the operation of the MAX5774 32-channel, 14-bit, voltage-output digital-to-analog converter (DAC). The DAC integrates an SPI™/DSP-compatible serial interface to control each channel output. Each DAC channel has its own programmable input, gain, and offset register, and its output voltage can be set in the -2.5V to +7.5V range.
The MAX5774 EV kit circuit includes USB-to-SPI communication circuitry that generates the proper SPI signals to program the DAC outputs.
The MAX5774 EV kit includes Windows® 2000/XP® and Windows Vista® (32-bit)-compatible software that provides a simple graphical user interface (GUI) for exercising the MAX5774 features.
The MAX5774 EV kit can also evaluate the MAX5773 and MAX5775. The MAX5773 has a 0 to +10V range, and the MAX5775 has a -5V to +5V range. To evaluate the MAX5773 or MAX5775, replace U1 with a MAX5773UCB+ or MAX5775UCB+.
