DAC43701集成电路（IC）的数模转换器（DAC）规格书PDF中文资料

DAC43701属于集成电路（IC）的数模转换器（DAC）。由德州仪器制造生产的DAC43701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 automotive-grade 10-bit DAC53701-Q1 and 8-bit

DAC43701-Q1 (DACx3701-Q1) are a pin-compatible

family of buffered voltage-output smart digital-toanalog

converters (DACs). These devices consume

very low power, and are available in a tiny 8-pin

WSON package. The feature set combined with the

tiny package and low power make the DACx3701-

Q1 an excellent choice for applications such as

automotive tail plus brake light, license plate light

fade-in fade-out, and PWM expansion for interior light.

These devices have nonvolatile memory (NVM), an

internal reference, a PMBus-compatible I2C interface,

and a general-purpose input. The DACx3701-Q1

operates with either an internal reference or with the

power supply as a reference, and provides a full-scale

output of 1.8 V to 5.5 V.

The DACx3701-Q1 are smart DAC devices because

of the advanced integrated features. With a forcesense

output, GPI based function trigger, PWM

output, and NVM capabilities, smart DACs enable

system performance and control without the use of

software.
