After connecting your VP-427A, connect its power and thenswitch on the power to each device.To connect the VP-427A as illustrated in the example in Figure 2:1. Connect the output from an HDBaseT transmitter (for example, a TP-582T)to the HDBT IN RJ-45 connector.2. Connect the AUDIO OUT3.5mm mini jack connector to an unbalancedstereo audio acceptor (for example, an amplifier).3. Connect the HDMI OUT connector to an HDMI acceptor (for example, adisplay).4. Connect an IR receiver to the IR IN 3.5mm mini jack.5. Connect the IR OUT 3.5mm mini jack to an IR emitter.6. Connect the RS-232 9-pin D-sub connector to an RS-232 port (for example,a display).7. Connect the 5V DC power adapter to the power socket and connect theadapter to the mains electricity (not shown in Figure 2).Figure 2: Connecting the VP-427A HDBaseT to HDMI+Audio Receiver/Scaler4.1 RS-232 Control over HDBaseTYou can connect to the transmitter/receiver system via an RS-232 connectionusing, for example, a PC. Note that a null-modem adapter/connection is notrequired.To connect a PC via RS-232, connect the RS-232 9-pin D-sub rear panel port onthe transmitter/receiver system unit via a 9-wire straight cable (only pin 2 to pin 2,pin 3 to pin 3, and pin 5 to pin 5 need to be connected) to the RS-232 9-pin D-subport on your PC.Figure 2 shows RS-232 bidirectional control of the DVD that is connected to aTP-582T.4.2 IR Control Over HDBaseTSince the IR signal on the TP-582T transmitter and VP-427A receiver isbidirectional, you can use a remote control transmitter (that is used for controllinga peripheral device, for example, a DVD player) to send commands (to the AVequipment) from either end of the transmitter /receiver system. To do so, you haveto use the Kramer external IR sensor on one end (P/N: 95-0104050) and theKramer IR emitter cable on the other end (P/N: C-A35/IRE-10)Two IR Emitter Extension Cables are also available: a 15 meter cable and a 20 meter cable.The example in Figure 2 illustrates how to control the DVD player that isconnected to TP-582T using a remote control, via the VP-427A. In this example,the External IR Sensor is connected to the IR connector of the VP-427A and an IREmitter is connected between the TP-582T and the DVD player. The DVD remotecontrol sends a command while pointing towards the External IR Sensor. The IRsignal passes through the TP cable and the IR Emitter to the DVD player, whichresponds to the command sent.5 Operating the VP-427AThe VP-427A is operated directly using the front panel buttons and the OSD menu(see Section ‎5.2).5.1 Operating the VP-427A from the Front Panel ButtonsDuring normal operation (without the OSD), the front panel buttons perform thefollowing functions:∙Pressing MENU opens the on-screen display (OSD) main menu (seeSection ‎5.2), the next press closes the OSD∙Pressing +/FREEZE freezes the display, the next press unfreezes the display∙Pressing MENU and –/AUTO ADJUST together resets the display to 720p∙Pressing ENTER and +/FREEZE together resets the display to XGA5.2 Using the OSDYou can use the OSD to set a wide variety of parameters. When the MENU buttonis pressed, the main menu opens (see Section ‎5.2.2) allowing access to all thedevice settings.5.2.1 Operating the OSD from the Front Panel ButtonsWhile the OSD is open, the front panel buttons perform the following functions:∙Pressing - and + move forward and backward through the menu items and decrement or increment the parameter values∙Pressing ENTER selects and activates a menu item or accepts theparameter value set∙Pressing MENU closes the OSD menuThe menu times out by default after 10 seconds. To change the OSD display time,adjust the OSD/TIMER parameter.As an example of setting parameters, to increase the contrast on the display:1. From normal operation, press MENU.The OSD main menu appears on the screen.2. Press the + or – button to highlight CONTRAST.CONTRAST changes to green when highlighted.3. Press ENTER.The contrast value parameter changes to red.4. Press the + button to increase the value (increase the contrast) orthe – button to decrease the value (decrease the contrast).The value ranges from 0 to 100.5. Press ENTER to set the value.The contrast value parameter changes back to white.6. To return to normal operation, highlight EXIT and press ENTER, pressMENU, or wait until the menu times out.5.2.26 Technical Specifications6.1 Input Resolutions SupportFor the latest information on our products and a list of Kramer distributors, visit our Web site where updates to this user manual may be found.

THS4271集成电路实验特性及其应用摘要：以TI公司生产的集成运放THS4271为基础搭建实验测试电路，在定义的条件下实验，分别测量了运放的输入失调电压UIO，输入失调电流IIO，共模抑制比CMRR，开环差模放大倍数AUd等主要参数。

同时对测量的数据对应的相应的参数进行了简单分析。

基于THS4271的单位增益稳定，低失真，高压摆率等特性，举出几个应用实例，来说明其在某些工程领域有一定的应用价值，供今后的使用者参考。

关键词：THS4271；集成运放；实验；应用虽然经过多年的发展，在现代集成电路与系统芯片(Systemon Chip，SoC)中，集成电路运算放大器的应用依然非常广泛，并往往由应用需要对其性能提出苛刻的要求。

因此围绕高性能集成电路运算放大器的研究经久不衰。

文中结合实际项目的需要，对THS4271集成运放的主要参数进行了测试，并对结果和其应用进行了讨论，利于今后实验的开展，同时为器件的使用者提供参考。

1 芯片介绍THS4271是TI公司生产的低噪声，高压摆率，单位增益稳定电压反馈放大器，其设计正常工作电压范围是5～15 V。

兼有低噪声，高压摆率，宽带宽，低失真以及单位增益稳定的特性，使得THS4271具有高性能的表现。

此放大器的使用者可以在一个较宽的频带上获得实验所需的较高的动态范围，而不必为放大器在失偿期间的稳定性担忧。

该系列的放大器的封装形式有SOIC，带有PowerPAD的MSOP，以及带PowerPAD无引线的MSOP。

THS4271典型特征参数如表1所示。

THS4271原件形状，引脚分布及各引脚功能如图1所示。

(其中NC代表悬空)2 实验原理2．1 输入失调电压理想运算放大器(简称运放)的输入信号为零时，其输出直流信号也应该为零。

但实际上如果没有外界的调零措施，由于运放内部参数不完全对称，输出电压往往不为零。

这种输入为零时输出不为零的现象称为集成运放的失调。

在室温和标准电源电压下，为了使输出端的直流电压为零，必须先在输入端加一个直流电压作为补偿电压，以抵消偏离零点的输出电压，而这个加在输入端的电压即被称为输入失调电压UIO。
