Overview
The DAC8814IBDBTG4 is a quad, 16-bit, current-output digital-to-analog converter (DAC) designed and manufactured by Texas Instruments. This device operates from a single +2.7-V to 5.0-V supply, making it versatile for various applications. The DAC8814 features an external reference input voltage (VREF) that determines the full-scale output current, and it includes an internal feedback resistor (RFB) for temperature tracking when used with an external I-to-V precision amplifier. The device is packaged in a 28-pin SSOP (Shrink Small Outline Package) and is suitable for a wide range of operating temperatures from -40°C to +85°C.
