36-V digital potentiometers support wide signal swings and high power-supply voltages
Additionally, the MCP41HV31 and MCP41HV51 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. The 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.
Availability and Pricing
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.
