Datasheet TC1320 (Microchip)

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 • ±2 LSB INL digital-to-analog converter (DAC). The DAC produces • ±0.8 LSB DNL an output voltage that ranges from ground to an exter- 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, • Simple SMBus/I2CTM 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 • 8-Pin SOIC and 8-Pin MSOP Packages that the device starts at a known condition. Communication with the TC1320 is accomplished via a
Applications
