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, 5×5 mm QFN packages. The MCP41HV31 is $0.99 each and the MCP41HV51 is $1.09 each, in 5,000-unit quantities.
