DAC8830中文资料16 位、单通道、超低功耗、电压输出 DAC数据手册TI规格书

描述 Description

The DAC8830 and DAC8831are single, 16-bit, serial-input, voltage-output digital-to-analog converters (DACs) operating from a single 3 V to 5 V power supply. These converters provide excellent linearity (1 LSB INL),low glitch,low noise, and fast settling(1.0 µS to 1/2 LSB of full-scale output) over the specified temperature range of -40°C to +85°C. The output is unbuffered, which reduces the power consumption and the error introduced by the buffer.
These parts feature a standard high-speed (clock up to 50 MHz), 3 Vor 5 V SPI serial interface to communicatewith a DSP or microprocessor.
The DAC8830 output is0 V to VREF. However, the DAC8831 provides bipolar output (±VREF) when working with an external buffer.The DAC8830 and DAC8831 are both reset to zero code after power up. For optimum performance, a set of Kelvin connections to external reference and analog ground input are provided on the DAC8831.
The DAC8830 is available in an SO-8 package, and the DAC8831 in an SO-14 package.Both have industry standard pinouts. The DAC8831 is also available in a QFN-14 package.

简介

DAC8830属于集成电路（IC）的数模转换器（DAC）。由TI制造生产的DAC8830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。
