Texas Instruments DACx1401 High-Voltage-Output DACs
Texas Instruments DACx1401 High-Voltage-Output Digital-to-Analog Converters (DACs) are a pin-compatible family of single-channel, buffered, high-voltage output digital-to-analog converters (DACs) with an integrated 2.5V internal reference. These devices are specified monotonic and provide an exceptional linearity of less than 1LSB (maximum).
The DACx1401 offers bipolar output voltages of ±20V, ±10V, ±5V, and full-scale unipolar output voltages of 40V, 10V, and 5V. The DAC output range is programmable. The DACx1401 incorporates a power-on-reset (POR) circuit that powers up the DAC output and keeps the device in power-down mode until the outputs are enabled.
Communication with the devices is done through a high-speed, 4-wire serial interface compatible with industry-standard microprocessors and microcontrollers that support 1.7V to 5.5V operation. The Texas Instruments DACx1401 are characterized for operation over the temperature range of -40°C to +125°C and are available in a small 20-pin TSSOP package.
