DAC7741YB/250集成电路（IC）的数模转换器（DAC）规格书PDF中文资料

DAC7741YB/250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DAC7741YB/250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 DAC7741 is a 16-bit Digital-to-Analog Converter (DAC)

which provides 16 bits of monotonic performance over the

specified operating temperature range and offers a +10V,

low-drift internal reference. Designed for automatic test equipment

and industrial process control applications, the DAC7741

output swing can be configured in a ±10V, ±5V, or +10V

range. The flexibility of the output configuration allows the

DAC7741 to provide both unipolar and bipolar operation by

pin strapping. The DAC7741 includes a high-speed output

amplifier with a maximum settling time of 5μs to ±0.003%

FSR for a 20V full-scale change and only consumes 100mW

(typical) of power.

The DAC7741 features a standard 16-bit parallel interface with

double buffering to allow asynchronous updates of the analog

output and data read-back to support data integrity verification

prior to an update. A user-programmable reset control allows

the DAC output to reset to min-scale (0000H) or mid-scale

(8000H) overriding the DAC register values. The DAC7741 is

available in a LQFP-48 package and four performance grades

specified to operate from 0°C to +70°C and –40°C to +85°C.
