Overview
The DAC3174IRGCR is a dual-channel, 14-bit digital-to-analog converter (DAC) produced by Texas Instruments. This device is designed for high-speed applications, offering a maximum sample rate of 500 MSPS. It features a 14-bit resolution and uses low-voltage differential signaling (LVDS) for the digital input interface. The DAC3174IRGCR is pin compatible with other Texas Instruments DAC models such as the DAC3154, DAC3164, DAC3151, DAC3161, and DAC3171, making it a versatile option for various system designs. The device is packaged in a 64-pin VQFN PowerPAD™ package and operates over the full industrial temperature range of –40°C to +85°C.
