Texas Instruments DAC80516 Digital-to-Analog Converters (DACs)

Texas Instruments DAC80516 Digital-to-Analog Converters (DACs) are low-power, 16-channel, and buffered voltage-output DACs. These DACs with user-selectable gain configurations can provide full-scale outputs of 2.5V or 5V. The DAC80516 DACs include a 2.5V 5ppm/°C internal reference eliminating the need for external precision reference in various applications. These DACs communicate through an SPI and I2C-supported serial interface, operating at clock rates of up to 50MHz (during SPI writes to the device). The DAC80516 DACs are ideal for optical modules, inter-DC interconnects, and analog output modules.
