First low-power Digital-to-Analog converter simplifies Handheld designs by including nonvolatile memory

The MCP47/48FxBx8 family of octal 12-bit DACs, the first of their kind to include nonvolatile 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. Implementing multi-channel system control or signal outputs using Digital-to-Analog Converters (DACs) in today’s portable and handheld industrial, communications, consumer and medical systems has been difficult to do without significant processor overhead for device configuration during power-up. The answer to this problem is the MCP47/48FxBx8.

Handhelds and other portable systems are expected to deliver more capabilities in smaller, simpler designs. We help achieve this goal with the first DACs that eliminate processor overhead during power-up and provide the channel density, low power consumption and integrated features that today’s compact systems need so they can operate over longer periods using smaller, lighter batteries.
