20 pcs - MCP4161-502E/SN MCP4161-502E/SN, Digital Potentiometer 5kΩ 257-Position Linear Serial-SPI 8 Pin, SOIC

MCP414x/416x/424x/426x Digital PotentiometersThe Microchip MCP413x, MCP415x, MCP423x and MCP425x range of devices are Digital Potentiometers with a SPI interface and EEPROM memory.Featured is WiperLock Technology, providing a method of ’locking’ the wiper configuration. To unlock a high-voltage command is required (>,8.5 V), protecting the setting during normal operation.7-bit (129 steps) and 8-bit (257 steps) versions are available in various RAB resistance options from 5 kΩ to 100 kΩ. Further variants also give the choice between Rheostat and Potentiometer pinouts, Single and Dual Resistor Network options are also available.FeaturesZero Scale to Full-Scale Wiper OperationLow Wiper Resistance: 75 Ω (typical)Low Temperature Coefficient: Absolute (Rheostat) 50 ppm, Ratiometric (Potentiometer) 15 ppm (typical)Automatic Recall of Saved Wiper SettingWiperLock TechnologySPI Serial InterfaceResistor Network Terminal Disconnect FeatureBrown-Out Reset Protection: 1.5 V (typical)Serial Interface Inactive Current: 2.5 μA (typical)High-Voltage Tolerant Digital Inputs: Up to 12.5 VSupports Split Rail ApplicationsInternal Weak Pull-Up on all Digital InputsWide Operating Voltage: 1.8 V to 5.5 VWide Bandwidth (-3 dB) Operation: 2 MHz for 5.0 kΩ device (typical)Model VariantsPotentiometer Wiper Configuration: MCP4141, MCP4161, MCP4241, MCP4261Rheostat Wiper Configuration: MCP4142, MCP4162, MCP4242, MCP4262Single Resistor Network: MCP4141, MCP4142, MCP4161, MCP4162Dual Resistor Network: MCP4241, MCP4242, MCP4261, MCP42627-bit, 128 Resistors (129 steps): MCP4141, MCP4142, MCP4241, MCP41428-bit, 256 Resistors (257 steps): MCP4161, MCP4162, MCP4261, MCP4162Digital Potentiometer - Microchip
