Description
The 16-bit DAC81401 and 12-bit DAC61401
(DACx1401) are a pin-compatible family of single-
channel, buffered, high-voltage-output digital to-
analog converters (DACs) with an integrated 2.5-
V internal reference. These devices are specified
monotonic and provide exceptional linearity of less
than 1 LSB.
Get Started
1. Order the EVM.
2. Configure EVM jumpers.
3. Install DAC814xxEVM GUI from ti.com.
