DAC0800LCMX/NOPB集成电路（IC）的数模转换器（DAC）规格书PDF中文资料

DAC0800LCMX/NOPB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DAC0800LCMX/NOPB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 DAC0800 series are monolithic 8-bit high-speed

current-output digital-to-analog converters (DAC)

featuring typical settling times of 100 ns. When used

as a multiplying DAC, monotonic performance over a

40 to 1 reference current range is possible. The

DAC0800 series also features high compliance complementary current outputs to allow differential

output voltages of 20 Vp-p with simple resistor loads.

The reference-to-full-scale current matching of better

than ±1 LSB eliminates the need for full-scale trims in

most applications, while the nonlinearities of better than ±0.1% over temperature minimizes system error

accumulations.

The noise immune inputs will accept a variety of logic

levels. The performance and characteristics of the

device are essentially unchanged over the ±4.5V to

±18V power supply range and power consumption at

only 33 mW with ±5V supplies is independent of logic

input levels.

The DAC0800, DAC0802, DAC0800C and

DAC0802C are a direct replacement for the DAC-08,

DAC-08A, DAC-08C, and DAC-08H, respectively. For

single supply operation, refer to AN-1525.
