Microchip claims to have overcome the problems of implementing multi-channel system control or signal outputs using DACs in portable and handheld industrial, communications, consumer or medical systems. To overcome the need for significant processor overhead for device configuration during power-up, the MCP47/48FxBx8 family of octal 12-bit DACs include non volatile memory and an integrated voltage reference (Vref) source so they can be pre-configured for safe and efficient power-up without relying on the system processor.
