DAC7612U/2K5集成电路（IC）的数模转换器（DAC）规格书PDF中文资料

DAC7612U/2K5属于集成电路（IC）的数模转换器（DAC）。由美国德州仪器公司制造生产的DAC7612U/2K5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。

DESCRIPTION

The DAC7612 is a dual, 12-bit digital-to-analog converter

(DAC) with guaranteed 12-bit monotonicity

performance over the industrial temperature range. It

requires a single +5V supply and contains an input

shift register, latch, 2.435V reference, a dual DAC, and

high speed rail-to-rail output amplifiers. For a fullscale

step, each output will settle to 1 LSB within 7ms

while only consuming 3.7mW.

The synchronous serial interface is compatible with a

wide variety of DSPs and microcontrollers. Clock

(CLK), Serial Data In (SDI), Chip Select (CS) and

Load DACs (LOADDACS) comprise the serial interface.

The DAC7612 is available in an 8-lead SOIC package

and is fully specified over the industrial temperature

range of –40°C to +85°C.
