描述 Description

The MAX5152/MAX5153 low-power, serial, voltage-output, dual 13-bit digital-to-analog converters (DACs) consume only 500μA from a single +5V (MAX5152) or +3V (MAX5153) supply. These devices feature Rail-to-Rail output swing and are available in space-saving 16-pin QSOP and DIP packages. Access to the inverting input allows for specific gain configurations, remote sensing, and high output current capability, making these devices ideally suited for industrial process controls. These devices are also well suited for digitally programmable (4-20mA) current loops.
The 3-wire serial interface is SPI?/QSPI? and MICROWIRE? compatible. Each DAC has a double-buffered input organized as an input register followed by a DAC register, which allows the input and DAC registers to be updated independently or simultaneously. Additional features include a programmable shutdown (2μA), hardware-shutdown lockout, a separate voltage reference for each DAC, power-on reset, and an active-low clear input (active-low CL) that resets all registers and DACs to zero. The MAX5152/MAX5153 provide a programmable logic output pin for added functionality, and a serial-data output pin for daisy chaining.

簡(jiǎn)介

MAX5153屬于集成電路（IC）的數(shù)模轉(zhuǎn)換器（DAC）。由制造生產(chǎn)的MAX5153數(shù)模轉(zhuǎn)換器（DAC）數(shù)模轉(zhuǎn)換器（DAC、D/A、D2A 或 D 轉(zhuǎn) A）可將數(shù)字信號(hào)轉(zhuǎn)換為緩沖或無(wú)緩沖的模擬電壓或電流。DAC 架構(gòu)是否適合特定應(yīng)用，要取決于分辨率和采樣頻率。DAC 通常用于音樂(lè)播放器，將數(shù)字?jǐn)?shù)據(jù)流轉(zhuǎn)換為模擬音頻流。它們還用于電視和手機(jī)，將數(shù)字視頻數(shù)據(jù)轉(zhuǎn)換為模擬視頻信號(hào)，再連接到屏幕驅(qū)動(dòng)器，以顯示單色或彩色圖像。
