Overview
The DAC8811IBDRBT is a 16-bit, single-channel, serial input multiplying digital-to-analog converter (DAC) produced by Texas Instruments. This device is designed to operate from a single 2.7-V to 5.5-V supply, making it versatile for various applications. The DAC8811 features a high-speed 3-wire serial interface compatible with most DSPs, with a serial clock frequency of up to 50 MHz. It includes an internal feedback resistor (RFB) and a reference input pin (VREF) that determines the full-scale output current. The device is packaged in an 8-pin VSON (DRB) package, which is space-efficient and suitable for compact designs.
