DAC7678SPWR

The DAC7678SPWR is an integrated circuit from Texas Instruments that functions as a 12-bit digital-to-analog converter (DAC). It provides 8 channels of voltage output with buffered voltage type, suitable for applications requiring multiple precise voltage outputs. The device uses a String DAC architecture and supports both external and internal reference types, with an internal reference voltage of 2.5V. It operates within a voltage range of 2.7V to 5.5V and can withstand temperatures from -40°C to 125°C.

The device features a settling time of 12 microseconds and an integral non-linearity (INL) of ±0.3 or ±0.1, depending on the measurement. It has a relative accuracy of 1 LSB and an INL of 0.15nV-s, indicating high precision. The DAC supports I²C data interface and has a sink/source capability of 20mA. Power consumption is low at 0.13mA per channel, making it suitable for low-power applications. The package is a 16-TSSOP surface-mount type, with a quantity of 90 units per tube.

This DAC is used in data acquisition systems, instrumentation, and control applications where multiple voltage outputs are necessary. Its design allows for high accuracy and stability over a wide temperature range, making it suitable for industrial and laboratory environments.
