DAC7678SPWR

Digital To Analog Converters Overview

The DAC7678SPWR is an octal, 12-bit digital-to-analog converter manufactured by Texas Instruments. It features a serial I2C-compatible interface and operates within a supply voltage range of 2.7 V to 5.5 V for both analog and digital domains. The device provides buffered voltage outputs with a settling time of 12 µs and a sampling rate of 55.55 kS/s. Key performance metrics include a differential nonlinearity (DNL) of ±0.1 LSB and integral nonlinearity (INL) of ±0.3 LSB. It is housed in a 16-pin TSSOP package and supports an operating temperature range from -40°C to +125°C.
