Product Details

The AD5750 is a single-channel, low cost, precision current/ voltage output driver with hardware- or software-programmable output ranges. The software ranges are configured via an SPI-/MICROWIRE®-compatible serial interface.

The output current range is programmable across five current ranges: 4 mA to 20 mA, 0 mA to 20 mA, 0 mA to 24 mA, ±20 mA, and ±24 mA.

Voltage output is provided from a separate pin that can be configured to provide 0 V to 5 V, 0 V to 10 V, ±5 V, or ±10 V output ranges. An overrange of 20% is available on the voltage ranges.

The input to the AD5750 is an analog input ranging from 0 V to 4.096 V. After the range is selected, 0 V outputs the low end of the selected range, and 4.096 V outputs the high end of the selected range. This evaluation board is configured to allow the AD5750 to be driven with an on-board DAC (AD5662 16-bit, 0 V to 4.096 V output). Alternatively, the user can configure an external 0 V to 4.096 V input. The evaluation board can operate the AD5750 in software mode only.

The evaluation board is powered via terminal blocks and requires a sense resistor (R38) of 15 kΩ with less than 15 ppm/°C; there is no load resistor provided on this evaluation board.
