Abstract: This article discusses application circuits for Maxim force/sense digital-to-analog converters (DACs). Applications include: selectable fixed-gain DAC, programmable gain DAC, photodiode bias control, amperometric sensor control, ...

Abstract: This design idea describes a simple circuit that converts a 4-20mA signal to a 0V to 5V analog voltage ideal for conversion to digital with an analog-to-digital converter (ADC). The 4mA level from the transducer produces a 0V out...

摘要：ANSI EIA/TIA-644標(biāo)準(zhǔn)定義的低電壓差分信號(hào)(LVDS)非常適合包括時(shí)鐘分配、點(diǎn)對點(diǎn)以及多點(diǎn)之間的信號(hào)傳輸。本文描述了使用LVDS將高速通訊信號(hào)分配到多個(gè)目的端的方法。 ...

摘要：與ECL、PECL和CML標(biāo)準(zhǔn)相比，ANSI EIA/TAI-644的低電壓差分信號(hào)(LVDS)標(biāo)準(zhǔn)具有低功耗、低噪聲輻射等優(yōu)勢。本文主要討論LVDS的特性及其可能的應(yīng)用。 最近幾年，隨著微...

Abstract: The DS1868 uses a dual digital potentiometer with a 3-wire (shift register) interface. This application note describes the logic and firmware required to interface the DS1868, as well as any other Dallas Semiconductor 3-wire devi...

Abstract: Design idea outlining how to use an I2C-controlled analog switch to triple the number of devices connected to an I2C bus. Perhaps the most effective way to gain board space and increase component density is to m...

摘要：本文討論EIA/TIA-644低壓差分信號(hào)(LVDS)標(biāo)準(zhǔn)在3G移動(dòng)通信設(shè)備中的應(yīng)用，LVDS具有低功耗、低輻射等優(yōu)勢，可理想用于W-CDMA、EDGE和CDMA2000中的高速時(shí)鐘、數(shù)據(jù)傳輸。 3G...

Abstract: A circuit is described that allows four remote RS-232 transceivers to share a single UART. A dual four-to-one multiplexer permits transceiver IC1 to form a network with the four remote transceivers. RS-232 commu...

OverviewIn a typical application the SCSI devices are daisy-chained as shown in Figure 1. The DIFFCAP signal monitors the DIFFSENS line to determine the proper operating mode of the device. The DIFFSENSE pin can also drive the SCS...

Abstract: Analog switches can be used to enable the transmission of digital signals and power over the same two wires. The signal waveform is rectified at the remote location to provide a stable supply voltage and modest load current (abou...

Abstract: SCSI terminators are used to match the termination impedance at each end of a SCSI bus. Matching the impedance is important to maximize the data transfer rate by reducing ringing and cross-talk between cable pairs. ...

The choice of SCSI (Small Computer System Interface) transceivers, whether single-ended (SE) or differential (HVD or LVD), determines the speed of data transfers, the length of cable, and the number of devices that can be supported by a ho...

摘要：該應(yīng)用筆記介紹了一個(gè)可以免費(fèi)下載的PC程序，用于評估MAX7300和MAX7301 GPIO (擴(kuò)展口)的功能。 MAX7300和MAX7301是通用的28端口、通用輸入/輸出口(GPIO)處理器外設(shè)。通...

Abstract: This circuit provides flexible fault protection for a 4-20mA current loop. In addition, it includes circuitry for recovering digital signals (such as the HART protocol) imposed on the loop. 4-20mA current loops ...

Abstract: IrDA is a standardized, wireless, infrared data communications method. Modern products often support RS-232 alongside IrDA, meeting legacy requirements. This application note describes ways to achieve both interfaces with a singl...

摘要：本文描述了SCSI、FAST SCSI和ULTRA SCSI之間的差別，給出了DS2120 SCSI端接器的連接方式以及所需要的電平。本文還討論了DIFF_CAP、DIFFSENS相關(guān)的MSTR/SLV功能。 另請參考: S...

Abstract: A serial interface is often used for board-level communication between different integrated circuits, especially in space-constrained applications at low-to medium data-rates. The most popular serial interfaces are I²C and S...

利用串行-解串器能夠大大減少近距離、寬帶數(shù)據(jù)通信中的連線，類似的應(yīng)用有電信和網(wǎng)絡(luò)設(shè)備的背板互連、3G蜂窩電話基站中機(jī)架內(nèi)部的互連、數(shù)字視頻接口等。電流模式、低電壓...
