Microchip announced the first members of its new low-power family of Digital-to-Analog converters. The 12-bit resolution MCP4921 and the MCP4922 utilise a resistive string architecture, which provides low power consumption (350µA), low Differential NonLinearity (DNL) error (less than ±0.2LSB) and compact size (including the 8-pin MSOP package).
The high accuracy makes these devices ideal for set-point control applications used in a wide range of communications and hand-held battery-powered designs. The devices are controlled via an SPI™ interface, and operate from a supply of 2.7 to 5.5 Volts.
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 °C to +125 °C). Samples and volume production are available now.
