8-DIP machined IC socket allows to swap OPA2134 with many other dual opamp chips such as OPA2132, OPA2227, OPA2228, dual OPA132, OPA627, etc. Unlike other ESR Meters that only measure ESR value this one measures capacitor's ESR value as well as its capacitance all at the same time.Īudiophile headphone amplifier kit includes high quality audio grade components such as Burr Brown OPA2134 opamp, ALPS volume control potentiometer, Ti TLE2426 rail splitter, Ultra-Low ESR 220uF/25V Panasonic FM filtering capacitors, High quality WIMA input and decoupling capacitors and Vishay Dale resistors. It is an irreplaceable tool for troubleshooting and repairing electronic equipment by determining performance and health of electrolytic capacitors. It also analyzes transistor's characteristics such as voltage and gain. I also dealt with testing only under Linux.ĮSR Meter / Capacitance / Inductance / Transistor Tester KitĮSR Meter kit is an amazing multimeter that measures ESR values, capacitance (100pF - 20,000uF), inductance, resistance (0.1 Ohm - 20 MOhm), tests many different types of transistors such as NPN, PNP, FETs, MOSFETs, Thyristors, SCRs, Triacs and many types of diodes.

With RMAA for some reason, I reached under Windows 7 much worse than under Windows XP. parameters measurement programs I conducted RightMark Audio Analyzer (RMAA) and Baudline. The digital input can be used to connect other digital audio sources such as DAT, MiniDisc, CD player, etc. Wiring can be used as a second sound card, or as S / PDIF output to a stereo amplifier with digital input. In addition to the circuit PCM2902 are expensive optical transceivers and transformers. If you want to use just some of the inputs or outputs, it is not necessary to assemble all the connectors. Measured parameters approximately correspond to those in the data sheet. Krab1 Plastic Box U-23 mm x 54mm KP35B x 104 mmđpc Pulse transformer I got on Ebay and specifically PE-65612th If we do not mind that the input is not isolated, it can be replaced by two 100nF capacitors.Ĭ9-C14đ0uF/25V electrolyte SMD size BĖpcs USB connector GES Electronic and IC PCM2902 sell such as FK Technics. Most of the parts I got in GM Electronic. SMD components have a size 1206 and are positioned so that the well-soldered. After assembly, I discovered that the switch inputs is connected backwards. Its dimensions correspond to a plastic box U-KP35B. This allows us to its easy production in amateur conditions. PCB is designed as a one-sided with two wire jumpers. Then I placed a jumper wire, and all parts of the upper side and end connectors. Next I soldered the other circuits and I continued SMD resistors and capacitors. Excess tin I was easily suctioned copper wick, which is sold for this purpose. When I was sure that the circuit is properly positioned, so I nanesl on all pins liquid flux, which facilitates pouring tin and drove my soldering iron and tin cored first one side and then the other. Circuit I snapped two corner pins mikropájkou. First I soldered circuit IC1, which is really quite small already. We are placing PCB components from the smallest to largest.
They work well as HID buttons, volume control and mute.

I tried the full functionality in Linux, Windows XP, Windows 7 Drivers are included with the operating system. Analog output does not contain any external amplifier so you can not connect directly to such low impedance headphones. The circuit automatically switches from an analog to digital, if you will detect the presence of S / PDIF signal. The digital input is connected via switch electrical / optics. I had a better experience with a resistor before the transformer. Entry is zaterminován resistor R7, which can be placed before, or pulse transformer.

S / PDIF receiver also includes an RS422 driver involved in reverse this time as to TTL converter. The output divider is a little more tension, but it should not matter. Most of the shows the output voltage of 0.6V peak-peak. Since the transfer of commercial S / PDIF coaxial cable used with unbalanced 75 ohm impedance, so I used only one output and using the resistive divider R13/R14 I shrunk the output voltage and adjust the output impedance standard. Electrical S / PDIF output is realized using an RS422 transmitter IC4. The circuit is also connected to an optical transmitter and receiver TOTX173 TORX173. All supply voltages are blocked 1uF capacitors. For a better quality analog output is used with an external voltage regulator circuit IC2. Involvement is based on the recommended involvement of the data sheet.
