GENERAL DESCRIPTION
The AD73761 is one of the few high voltage, high performance
digital potentiometers2 on the market. This device can be used
as a programmable resistor or resistor divider. The AD7376
performs the same electronic adjustment function as mechanical
potentiometers, variable resistors, and trimmers with enhanced
resolution, solid-state reliability, and programmability. With
digital rather than manual control, the AD7376 provides layout
flexibility and allows closed-loop dynamic controllability.
The AD7376 features sleep-mode programmability in shutdown
that can be used to program the preset before device activation,
thus providing an alternative to costly EEPROM solutions.
The AD7376 is available in 14-lead TSSOP and 16-lead wide
body SOIC packages in 10 k, 50 k, and 100 k options. All
parts are guaranteed to operate over the 40°C to +85°C
extended industrial temperature range.
