DAC81404 Evaluation Module
Description
The 16-bit, 4-channel DAC81404 and 12-bit, 4-
channel DAC61404 are a pin-compatible family of
quad-channel, buffered, high-voltage-output digital-to-
analog converters (DACs) with an integrated 2.5V
internal reference. These devices are specified
monotonic and provide exceptional linearity of less
than 1LSB.
