General Description
The AS1506 is a linear, 256-tap digital potentiometer specifically designed to replace discrete/mechanical potentiometers and is ideal for applications requiring a low-temperature-coefficient variable resistor, such as low-drift, programmable gain, and amplifier circuit configurations.
