Low-Power, Low-Cost 6-bit Volatile DAC With Command Code Features 1.8-5.5V Wide Operating Voltage Range; I2C™and SMBus™ compatibility

Microchip Technology Inc., a leading provider of microcontroller, analog and Flash-IP solutions, today introduced the volatile MCP47A1 Digital-to-Analog Converter (DAC). This low-power, low-cost DAC features a 1.8-5.5V wide operating voltage range, and is offered in a 6-pin SC70 package. The MCP47A1 is ideal for applications in the automotive, audio and industrial markets, such as portable, handheld battery-operated products, and applications such as set-point or offset trimming and sensitive mechanical-trim pot replacement.

The extended temperature range of -40 to +125 degrees Celsius allows for use in high-temperature automotive and industrial applications. Additionally, the small SC70 packaging allows for more portable and space-constrained consumer applications. The MCP47A1 DAC also provides 65 taps, through an I²C™ interface, including taps to both full-scale and zero-scale, providing additional functionality. Low power consumption extends lifetimes in applications with finite power supplies, and the low cost is suitable for cost-sensitive applications.

“The MCP47A1 is optimized for system power reduction and cost reduction,” said Bryan J. Liddiard, vice president of marketing with Microchip’s Analog & Interface Products Division. “Because of its extended temperature range, this new DAC can also be used in high-temperature automotive and industrial applications.”
