Microchip Digital Potentiometers

Digital Potentiometers

Microchip’s large portfolio of Digital Potentiometers (DigiPots) service a broad range of precision-controlled applications. Our portfolio enables fine tuning with highly accurate, small form factor, digitally controlled resistor solutions. These low-power, compact devices feature six to eight bits of resolution, one- to four-channel counts and are available in both volatile and nonvolatile memory types to support a wide variety of design needs. Tiny packages such as SC-70 and DFN (2 x 3 mm) are offered for space-constrained systems. Our digital potentiometers offer better precision because of our Integral Nonlinearity (INL), total unadjusted error specs and increase in resolution. Microchip’s digital potentiometers minimize development risk and increase system performance by providing reliable, well-documented functionality and quick fixes for design flaws.

Nonvolatile
Automatic recall of potentiometer wiper settings for increased system performance
WiperLock™ technology for added EEPROM security
General purpose memory locations for calibration
High Voltage
+36V Terminal Voltage Range (DGND = V-)
±18V Terminal Voltage Range (DGND = V- + 18V)
High voltage provides support for applications using power rails from 10V to 36V or +/-5V to +/-18V
Automotive Recommened
Grade 1 extended temperature range: -40°C to +125°C
Digital technology eliminates the failure of mechanical POTs
Available in 6, 7 and 8-bit devices, volatile and nonvolatile
Additional electromagnetic filtering on select devices provide additional protection in electrically harsh environments
