MAX5191数据手册集成电路（IC）的数模转换器（DAC）规格书PDF

描述 Description

The MAX5188 is a dual 8-bit, alternate-phase-update,current-output digital-to-analog converter (DAC)designed for superior performance in systems requiringanalog signal reconstruction with low distortion andlow-power operation. The MAX5191 provides equalspecifications, with on-chip output resistors for voltage-output operation. Both devices are designed for 10pV-sglitch operation to reduce distortion and minimizeunwanted spurious signal components at the output. Anon-board +1.2V bandgap circuit provides a well-regulated,low-noise reference that may be disabled forexternal reference operation.
The MAX5188/MAX5191 are designed to provide a highlevel of signal integrity for the least amount of powerdissipation. Both DACs operate from a +2.7V to +3.3Vsingle supply. Additionally, these DACs have threemodes of operation: normal, low-power standby, andfull shutdown. A full shutdown provides the lowest possiblepower dissipation with a maximum shutdown currentof 1µA. A fast wake-up time (0.5µs) from standbymode to full DAC operation allows for power conservationby activating the DACs only when required.
The MAX5188/MAX5191 are available in a 28-pin QSOPpackage and are specified for the extended (-40°C to+85°C) temperature range. For pin-compatible 10-bitversions, refer to the MAX5182/MAX5185 data sheet.

简介

MAX5191属于集成电路（IC）的数模转换器（DAC）。由制造生产的MAX5191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。
