MCP4531T-104E/MS

Microchip MCP4531T-104E/MS is a 1-channel, volatile digital potentiometer with SPI interface and a 100 kΩ end-to-end resistance (104 = 100k). Key points:
- End-to-end resistance: 100 kΩ; wiper resolution: 8-bit (256 positions).
- Interface: SPI (CS, SCK, SI, SO) with A, B, W terminals plus VDD and VSS.
- Supply: 2.7 V to 5.5 V; low-power operation.
- Memory: Wiper position stored in volatile memory (not retained after power-down unless a non-volatile variant is used).
- Packaging: RoHS-compliant MS packaging; Tape & Reel available.
- Applications: adjustable gains/attenuation, calibration/trimming, programmable analog dividers and sensor front-ends.
- Note: For exact timing, current consumption, and electrical characteristics, consult the datasheet.
