MCP47/48FxBx8 12-bit Analog to Digital Converters from Microchip

Microchip has introduced the MCP47/48FxBx8 family of octal 12-bit DACs (Digital-to-Analog Converters), that come with non-volatile memory and an integrated voltage reference (Vref) source. The new device is designed to eliminate the significant processor overhead for device configuration while implementing multi-channel system control or signal outputs using DACs.

The non-volatile memory of the device allows it to store user-customized configuration data even when powered down, when powered up all eight channels will be configured to the pre-defined state. The integrated Vref source reduces overall system size and complexity while providing the necessary control to meet critical timing needs for safely driving all power outputs.

The low minimum operating voltage of 1.8V to 5.5V and a high level of power efficiency of the device help provide better thermal performance and reliability. The device is designed with power-on/brown-out to reset protection and operates at an extended temperature range (-40 °C to +125 °C). This makes the MCP47/48FxBx8 DACs suitable for industrial and automotive applications.

The MCP47/48FxBx8 DAC family includes 8-, 10-, and 12-bit resolution devices in a 20-lead VQFN 5 x 5 mm package and a 20-lead TSSOP package. The company is accepting volume orders of MCP47/48FxBx8 family and the pricing starts at $2.47 each in 5,000-unit volumes.
