描述 Description

The DAC5571 is a low-power, single-channel, 8-bit buffered voltage output DAC. Its on-chip precision output amplifier allows rail-to-rail output swing to be achieved. The DAC5571 utilizes an I2C-compatible, two-wire serial interface that operates at clock rates up to 3.4 Mbps with address support of up to two DAC5571s on the same data bus.
The output voltage range of the DAC is 0 V to VDD. The DAC5571 incorporates a power-on-reset circuit that ensures that the DAC output powers up at zero volts and remains there until a valid write to the device takes place. The DAC5571 contains a power-down feature, accessed via the internal control register, that reduces the current consumption of the device to 50 nA at 5 V.
The low-power consumption of this part in normal operation makes it ideally suited for portable battery operated equipment. The power consumption is less than 0.7 mW at VDD = 5 V reducing to 1 µW in power-down mode.
DAC7571/6571/5571 are 12/10/8-bit, single-channel I2C DACs from the same family. DAC7574/6574/5574 and DAC7573/6573/5573 are 12/10/8-bit quad-channel I2C DACs. Also see DAC8571/8574 for single/quad-channel, 16-bit I2C DACs.

简介

DAC5571属于集成电路（IC）的数模转换器（DAC）。由TI制造生产的DAC5571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。
