    产品信息

    MCP41HV31 is a single-channel, high voltage digital potentiometer (Digipot) family that supports 10V ~36V or +/-5V to +/-18V power rails. It features 7-bit resolution with SPI interface. This family is available in TSSOP-14 and QFN-20 (5x5) packages and has 5kΩ, 10 kΩ, 50 kΩ, and 100 kΩ end-to-end resistance(RAB) options . All parts are guaranteed to operate over  –40°C to +125°C extended temperature range.

    Microchip's MCP41HVX1 and MCP45HVX1 digital potentiometer (Digipot) families offer the widest operating voltage range that is currently available on the market.

      High-Voltage Analog Support:

      Low Tempco:

      Ratiometric (Potentiometer): 15 ppm Typical

      SPI Serial Interface(10 MHz, Modes 0,0 and 1,1)

      Resistor Network Terminal Disconnect Via:

      Shutdown Pin (SHDN)

      Terminal Control (TCON) Register

      Write Latch (WLAT) Pin to control update of Volatile Wiper Register (such as Zero Crossing)

      Power-On Rest / Brown-Out Reset for both:

      Digital Supply (VL/DGND); 1.5V Typical

      Analog Supply (V+ / V-); 3.5V Typical

      Serial Interface Inactive Current (3 µA Typical)

      3dB Bandwidth: 500 kHz Typical (5.0 kΩ Device)

      Extended Temperature Range (-40°C to +125°C)

      Package Types: TSSOP-14 and QFN-20 (5x5)
