TC1320 8-Bit Digital-to-Analog Converter with Two-Wire Interface Features General Description 8-bit Digital-to-Analog Converter The TC1320 is a serially accessible 8-bit voltage output digital-to-analog converter (DAC). The DAC produces 2 LSB INL an output voltage that ranges from ground to an exter- 0.8 LSB DNL nally supplied reference voltage. It operates from a sin- 2.7-5.5V Single Supply Operation gle power supply that can range from 2.7V to 5.5V, 2 TM Simple SMBus/I C Serial Interface making it ideal for a wide range of applications. Built Low Power: 350 A Operation, 0.5 A Shutdown into the part is a Power-on Reset function that ensures that the device starts at a known condition. 8-Pin SOIC and 8-Pin MSOP Packages Communication with the TC1320 is accomplished via a Applications 2 simple 2-wire SMBus/I C compatible serial port with the TC1320 acting as a slave only device. The host can Programmable Voltage Sources enable the SHDN bit in the CONFIG register to activate Digital Controlled Amplifiers/Attenuators the Low Power Standby mode.
