MCP4161 Datasheet PDF

●The MCP4161-103E/SN is a 8-bit (256 wiper steps) non-volatile Digital Potentiometer programmed/reprogrammed through an SPI compatible interface. This device offers WiperLock™ technology which allows the user unlimited reprogramming and locking of the wiper setting. This is useful for equipment that requires factory trimming or recalibration. WiperLock technology allows application-specific calibration settings to be secured in the EEPROM.

● 8-bit 256 Resistors with taps to VSS and VDD

● Automatic recall of potentiometer wiper settings

● <10ppm Typical absolute (rheostat) low tempco

● <10ppm Typical ratiometric (potentiometer) low tempco

● 100R Typical low wiper resistance

● WiperLock™ technology to secure the EEPROM

● 1µA Maximum static current low-power operation

● Zero to full-scale wiper operation

● Non-volatile memory - automatic recall of saved wiper setting

● Resistor network terminal disconnect feature via shutdown pin (SHDN)

● Write protect feature - hardware write protect (WP) control pin

● 1.5V Typical brown-out reset protection

● 2.5µA Typical serial interface inactive current

● Up to 12.5V high-voltage tolerant digital inputs

● Supports split rail applications

● Internal weak pull-up on all digital inputs

●ESD sensitive device, take proper precaution while handling the device.
