AD8300集成电路（IC）的数模转换器（DAC）规格书PDF中文资料

AD8300属于集成电路（IC）的数模转换器（DAC）。由亚德诺半导体技术有限公司制造生产的AD8300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。

GENERAL DESCRIPTION

The AD8300 is a complete 12-bit, voltage-output digital-to analog converter designed to operate from a single +3 volt supply. Built using a CBCMOS process, this monolithic DAC offers the user low cost, and ease-of-use in single-supply +3 volt systems. Operation is guaranteed over the supply voltage range of +2.7 V to +5.5 V making this device ideal for battery operated applications.

The 2.0475 V full-scale voltage output is laser trimmed to maintain accuracy over the operating temperature range of the device. The binary input data format provides an easy-to-use one-half-millivolt-per-bit software programmability. The voltage outputs are capable of sourcing 5 mA.

A double buffered serial data interface offers high speed, three wire, DSP and microcontroller compatible inputs using data in (SDI), clock (CLK) and load strobe (LD) pins. A chip select (CS) pin simplifies connection of multiple DAC packages by enabling the clock input when active low. Additionally, a CLR input sets the output to zero scale at power on or upon user demand.

The AD8300 is specified over the extended industrial (–40°C to +85°C) temperature range. AD8300s are available in plastic DIP, and low profile 1.5 mm height SO-8 surface mount packages.
