TC1321 Datasheet | Microchip Technology

Features - - - - - 10-Bit Digital-to-Analog Converter 2.7-5.5V Single Supply Operation Simple SMBus/I2CTM Serial Interface Low Power: 350µA Operation, 0.5µA Shutdown 8-Pin SOIC and 8-Pin MSOP Packages General Description The TC1321 is a serially accessible 10-bit voltage output digital-to-analog converter (DAC). The DAC produces an output voltage that ranges from ground to an externally supplied reference voltage. It operates from a single power supply that can range from 2.7V to 5.5V, making it ideal for a wide range of applications. Built into the part is a Power-on Reset function that ensures that the device starts at a known condition. munication with the TC1321 is acplished via a simple 2-wire SMBus/I2C patible serial port, with the TC1321 acting as a slave only device. The host can enable the SHDN bit in the CONFIG register to activate the Low Power Standby mode.
