description:
The MAX22007 is a quad-channel, 12-bit digital-to-analog converter (DAC)
with integrated precision output amplifiers and current output capability.
Each channel can be independently configured for voltage or current output.
Datasheet available at https://www.analog.com/en/products/max22007.html

description: Low-Voltage Power Supply from +2.7V to +5.5V.
hvdd-supply:
description:
Positive High-Voltage Power Supply from +8V to (HVSS +24V) for
the Output Channels.
hvss-supply:
description:
Optional Negative High-Voltage Power Supply from -2V to 0V for the Output
Channels. For most applications HVSS can be connected to GND (0V), but for
applications requiring output down to true 0V or 0mA, connect to a -2V supply.
