DAC3282中文资料双通道、16 位、625MSPS、1x-2x 内插数模转换器 (DAC)数据手册TI规格书

描述 Description

The DAC3282 is a dual-channel 16-bit 625 MSPS digital-to-analog converter (DAC) with an 8-bit LVDS input data bus with on-chip termination, optional 2x interpolation filter, and internal voltage reference. The DAC3282 offers superior linearity, noise and crosstalk performance.Input data can be interpolated by 2x through an on-chip interpolating FIR filter with over 85 dB of stop-band attenuation. Multiple DAC3282 devices can be fully synchronized.The DAC3282 allows either a complex or real output. An optional coarse mixer in complex mode provides frequency upconversion and the dual DAC output produces a complex Hilbert Transform pair. The digital offset correction feature allows optimization of LO feed-through of an external quadrature modulator performing the final single sideband RF up- conversion.The DAC3282 is characterized for operation over the entire industrial temperature range of –40°C to 85°C and is available in a 48-pin 7×7mm VQFN package.

简介

DAC3282属于集成电路（IC）的数模转换器（DAC）。由TI制造生产的DAC3282数模转换器（DAC）数模转换器（DAC、D/A、D2A 或 D 转 A）可将数字信号转换为缓冲或无缓冲的模拟电压或电流。DAC 架构是否适合特定应用，要取决于分辨率和采样频率。DAC 通常用于音乐播放器，将数字数据流转换为模拟音频流。它们还用于电视和手机，将数字视频数据转换为模拟视频信号，再连接到屏幕驱动器，以显示单色或彩色图像。
