MCP48x1/49x1 - 8/10/12-Bit Voltage Output DACs for more Flexibility
Microchip's new MCP48x1/MCP49x1 Digital-to-Analogue Converters (DACs) expand the Company’s portfolio of DACs with single- and dual-channel 8- and 10-bit devices featuring an SPI communication interface, as well as internal and external voltage-reference options.
The MCP48XX family has an internal voltage reference, while the MCP49XX family accepts an external voltage reference. These DACs are appropriate for applications in the consumer (e.g., home appliances, LCD displays, computer peripherals); industrial (e.g., control systems, motor control, metering); and medical markets (e.g., ultrasound, ECG, sensor calibration), among others.
Because the MCP48XX and MCP49XX DACs offer both 8- and 10-bit resolution, designers can select the resolution needed for different applications. Additionally, having an integrated voltage reference reduces cost and space, while the external pin provides further design flexibility. Availability in small packages also saves space and makes the DACs easy to use.
