DAC63002集成电路（IC）的数模转换器（DAC）规格书PDF中文资料

DAC63002属于集成电路（IC）的数模转换器（DAC）。由德州仪器制造生产的DAC63002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。

3 Description

The 12-bit DAC63001 and DAC63002, and the 10‑bit

DAC53001 and DAC53002 (collectively referred to as

the DACx300x) are a pin-compatible family of ultralow-

power, single-channel and dual-channel, buffered

voltage-output and current-output smart digital-toanalog

converters (DACs). The DACx300x devices

support Hi-Z power-down mode and Hi-Z output

during power-off conditions. The DAC outputs provide

a force-sense option for use as a programmable

comparator and current sink. The multifunction GPIO,

function generation, and NVM enable these smart

DACs for processor-less applications and design

reuse. These devices automatically detect I2C,

PMBus, and SPI interfaces and contain an internal

reference.

The feature set combined with the tiny package and

ultra-low power make these smart DACs an excellent

choice for applications such as land mobile radios,

pulse oximeters, notebook PCs, and other batteryoperated

applications for biasing, calibration, and

waveform generation.
