MCP41HV51T-502E/ST

MCP41HV51T-502E/ST Description

The MCP41HV51T-502E/ST from Microchip Technology is a high-voltage, single-channel digital potentiometer (digipot) with a 5kΩ resistance and 256 taps, offering precise analog adjustment via SPI interface. Designed for surface-mount applications, it operates across a wide voltage range (1.8V–5.5V logic, 10V–36V or ±5V–18V analog), making it versatile for mixed-voltage systems. Its volatile memory ensures dynamic recalibration, while the linear taper and ±20% tolerance provide consistent performance. The device is RoHS3 compliant and rated for MSL 1 (unlimited shelf life), suitable for industrial and automotive environments.

MCP41HV51T-502E/ST Features

• High-Voltage Operation: Supports up to 36V (or ±18V dual-supply), ideal for industrial control and power management.
• SPI Interface: Enables fast, daisy-chainable communication with microcontrollers.
• Low Wiper Resistance: 145Ω (typ) minimizes signal distortion in precision circuits.
• Wide Temperature Range: 100ppm/°C coefficient ensures stability across harsh conditions.
• Compact Package: 14-TSSOP saves board space in dense layouts.
• 256-Tap Resolution: Fine-grained adjustment for applications like calibration or feedback loops.
