12bit DACs are low
in size and consumption
Microchip has released the first members of its new low-power family of digital-to-analogue convertors (DACs)
The 12bit resolution MCP4921 and the MCP4922 use a resistive string architecture, which provides low power consumption (350uA), low differential nonlinearity (DNL) error (less than +/-0.2LSB) and compact size (including an 8-pin MSOP option). The high accuracy makes these devices ideal for setpoint control applications used in a wide range of communications and handheld battery-powered designs.
The devices are controlled via an SPI interface, and operate from a supply of 2.7 to 5.5V.
The MCP4921 (single channel) is available in an 8-pin PDIP, SOIC or MSOP package and the MCP4922 (dual channel) is available in a 14-pin PDIP, SOIC or TSSOP package and they are specified to operate over an extended temperature range (-40 to +125C).
Samples and volume production are available now.
