# MCP41HV51-503E/ST (Component)
## Description
High-Voltage SPI Digital Potentiometer – Single-channel 8-bit digital potentiometer for programmable gain control, industrial automation, instrumentation, audio equipment, sensor calibration, power supplies, and embedded analog signal conditioning. Features 50 kΩ nominal resistance with 256 wiper positions (8-bit resolution), a linear taper, and an SPI serial interface for precise digital control. Supports separate digital and analog supply rails, with a digital supply of 1.8 V to 5.5 V and an analog supply up to 36 V (10 V to 36 V single supply or ±5 V to ±18 V dual supply), making it suitable for high-voltage analog applications. Includes 145 Ω typical wiper resistance, 100 ppm/°C temperature coefficient, volatile memory, shutdown capability, and AEC-Q100 qualification for high-reliability environments. Operates over a −40°C to +125°C temperature range and is housed in a 14-pin TSSOP package.
