Microchip’s new 36V digital potentiometers support wide signal swings and high power-supply voltages

9 JUNE 2013

Microchip announces two new volatile, SPI digital potentiometers (digipots), the MCP41HV31 and MCP41HV51 (MCP41HVXX), which are its first to operate at 10, 12, 18, 24 and particularly 36 volts, for systems requiring wide signal swing or high power-supply voltages. Additionally, these digipots support both 7-bit and 8-bit resistor configurations, and a high terminal/wiper current, including the ability to sink/source up to 25 mA on all terminal pins for driving larger loads. These features, combined with an extended temperature range of -40°C to +125°C, make the MCP41HVXX well suited to a broad range of high-voltage and high-temperature applications, including those in the industrial, automotive and audio markets.
The MCP41HV31’s 7-bit resistor network resolution enables 127 resistors and 128 steps, while the MCP41HV51’s 8-bit configuration supports 255 resistors and 256 steps. Additionally, both digipots provide RAB resistance options of 5, 10, 50 and 100 kohms.

Key Facts:
• Also feature high terminal/ wiper current support and an extended temperature range
• Support for 7-bit or 8-bit resistor configurations
• Ability to sink/source up to 25 mA on all terminal pins enables driving of larger loads
• Ideal for high-voltage and high-temperature applications including industrial, automotive and audio

Both The MCP41HV31 and the MCP41HV51 digital potentiometers are available today for samples and volume production, in 14-pin TSSOP and 20-pin, 5×5 mm QFN packages.
