Microchip Introduces New Volatile, SPI Digital Potentiometers

Microchip Technology Inc., a leading provider of microcontroller, analog and Flash-IP solutions, today announced two new volatile, SPI digital potentiometers (digipots)—the MCP41HV31 and MCP41HV51 (MCP41HVXX)—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 for 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.
“With their support of the wide operating voltages and extended temperature ranges that are common in industrial and automotive power supplies, these new digital potentiometers allow Microchip to address a broader range of applications,” said Bryan J. Liddiard, marketing vice president of Microchip’s Analog and Interface Products Division. “In fact, these digipots are well suited to any application that operates on higher system voltages.”

Pricing & Availability

Both digital potentiometers are available today for samples and volume production, in 14-pin TSSOP and 20-pin, 5x5 mm QFN packages. The MCP41HV31 is $0.99 each and the MCP41HV51 is $1.09 each, in 5,000-unit quantities.
