DAC7578中文资料12 位、8 通道、超低毛刺脉冲、电压输出、2 线接口 DAC数据手册TI规格书

描述 Description

The DAC5578 (8 bit), DAC6578 (10 bit), and DAC7578 (12 bit) are low-power, voltage-output, octal channel, digital-to-analog converters (DACs). The devices are monolithic, provide good linearity,and minimize undesired code-to-code transient voltages (glitch). The devices use a versatile, 2-wire serial interface that is I2C-compatible and operates at clock rates of up to 3.4MHz. Multiple devices can share the same bus. The devices incorporate a power-on-reset (POR) circuit that ensures the DAC output powers up to zero-scale or midscale until a valid code is written to the device. These devices also contain a power-down feature, accessed through the serial interface, that reduces the current consumption of the devices to typically 0.42µA at 5V. Power consumption is typically 2.32mW at 3V, reducing to 0.68µW in power-down mode. The low power consumption and small footprint make these devices ideal for portable, battery-operated equipment. The DAC5578, DAC6578, and DAC7578 are drop-in and functionally-compatible with the DAC7678. All devices are available in a 4x4, QFN-24 package and a TSSOP-16 package.

简介

DAC7578属于集成电路（IC）的数模转换器（DAC）。由TI制造生产的DAC7578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。
