DAC80004IDMDT集成电路（IC）的数模转换器（DAC）规格书PDF中文资料

DAC80004IDMDT属于集成电路（IC）的数模转换器（DAC）。由德州仪器制造生产的DAC80004IDMDT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 DAC80004/70004/60004 (DACx0004) are highly

accurate, low-power, voltage-output, quad-channel,

16-, 14-, 12-bit digital-to-analog converters (DACs)

respectively. The DACx0004 devices are ensured

monotonic by design and offer excellent linearity of

less than 1 LSB (Max). The reference input of the

DAC is buffered internally using a dedicated

reference buffer.

The DACx0004 devices incorporate a power-on-reset

circuit that ensures the DAC output powers up at zero

scale or mid scale depending on status of the POR

pin and remains in this state until a valid code is

written to the device. These devices consume very

low current of 1 mA/channel making them ideal for

portable, battery-operated equipment. These devices

also contain a power-down feature that reduces

current consumption to typically 3 μA at 5 V.

The DACx0004 devices use a versatile 4- or 3-wire

serial interface that operates at clock rates up to 50

MHz. The DACx0004 devices also include a SDO pin

to daisy chain multiple devices. The interface is

compatible with standard SPI™, QSPI™, Microwire,

and digital signal processor (DSP) interfaces. The

DACx0004 devices are offered in easy-to-assemble

14-pin TSSOP packages or an ultra small 14-pin

VSON package and are fully specified over the

extended industrial temperature range of –40°C to

125°C.
