Microchip Technology Inc.'s new volatile MCP47A1 Digital-to-Analog Converter (DAC) is a low-power, low-cost DAC featuring a 1.8-5.5V wide operating voltage range in a 6-pin SC70 package. The MCP47A1 is designed 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 DAC is available today for sampling and volume production, at $0.42 each in 5,000-unit quantities.
