7- and 8-bit, non-volatile, quad digital potentiometers from Microchip

Microchip has introduced the MCP4341, MCP4342 (MCP434X), MCP4361 and MCP4362 (MCP436X), a new 7- and 8-bit, non-volatile, quad digital potentiometers delivers static current consumption of 5 microamperes (max.). The new devices are suitable for consumer and industrial applications, such as power-supply trim and calibration, set-point and process control, closed-loop servo control, PC peripherals, portable instrumentation, instrumentation offset adjust and signal conditioning.

An SPI interface controls the MCP434X/436X devices digitally, which eliminates the need for human interaction, which increases system accuracy, flexibility and manufacturing throughput while decreasing manufacturing costs. Digital control also provides high system flexibility than mechanical control. Non-volatile memory enables the digital potentiometers to retain their settings at power down, and their low static current consumption of just 5 microamperes (max.) helps to extend battery life.

"Customers are constantly looking for ways to reduce power consumption and design footprint, while increasing the accuracy and performance of their designs," said Bryan J. Liddiard, vice president of marketing with Microchip's Analog and Interface Products Division. "With static current consumption of just 5 microamperes (max.), and availability in small packages, the MCP434X and MCP436X digital potentiometers help designers achieve these goals."

Operating temperature range: - 40° C to 125° C
