Diy balanced line driver

 · Balanced Audio Line Driver (Unbalance to Balance Audio Signal Converter) Using DRV/SSM 19/01/ RAJ SHARMA. The Mini board converts unbalance Audio signal into balance audio signal, the project is based on SSM or DRV IC which are differential output amplifier that converts a single ended audio signal input to a balanced Estimated Reading Time: 3 mins. The inductance of ferrite beads F1-F2 react with the capacitance of C5-C6 to shunt RFI noise to the chassis, away from the audio circuit. U1 is a balanced line driver IC. The THAT Corp. , TI DRV, and SSM are all pin-compatible. IC Choices (Click a part number to see pricing and availability.) Balanced Input ICs. Description. This is the circuit diagram of a two channel audio line driver using the high performance dual opamp IC TSH22 from ST Microelectronics. The 25 MHz bandwidth, low distortion and high output current of the IC makes it possible to drive medium impedance loads at a high level of modulation. Here both of the opamps inside the IC are wired as non inverting Missing: balanced line.

The balanced line driver is Burr Brown OPA The input impedance is setup via R1 and R3, which is k. The buffer gain is determinded by R5, R6 and R7. Buffer gain = (1+2*R5/R6). (note: R12,R13 and R14 for the second buffer). The gain of the fully differential opamp OPA is R17/R Unbalanced to Balanced Line Converter: Home Studio Recording DIY Projects Unbalanced to Balanced Line Converter. This circuit will convert unbalanced audio lines to balanced audio lines. Here's the schematic diagram using NE dual opamp chips, some resistors and capacitors. Balanced Line Driver THAT’s Balanced Line Driver is a very simple IC to implement, requiring very few external components. A complete schematic, including RFI protection and power supply bypassing, is shown in Fig. 6. A stereo pair will fit on the D4 prototyping board with room to spare; IC sockets are optional.
