COB Format TDA1541A Special Edition OP-AMP OUTPUT Operational Amplifier Output for DAC Blank Board PCB, TDA1541 Description

Color: As shown

TDA1541, TDA1541A, TDA1541R1, TDA1541AS1, TDA1241AS2, and TDA1541AS7 special version PCB blank boards. Currently, the test samples use OPA128 operational amplifiers for I/V conversion and LPF filter buffer output. When selecting a substitute for OPA128 in actual assembly, it is necessary to confirm whether its 8th pin is in a grounded state. The 8th pin of the OPA128 this motherboard is directly connected to ground, so please pay close attention to this! If the substitute's 8th pin is an OFFSET pin, it needs to be left unsoldered. The TDA1541 pin filter capacitors, high-frequency filter capacitors, and LPF decoupling capacitors all use 10mm-pitch packaged capacitors. The test capacitors for the motherboard are from the red for WIMA German for MKP series. The test resistors use 0.5W German for ERO blood-red resistors. The test coupling, or filter capacitors, use old-style for bakelite case capacitors. In actual testing, the OPA128 is very transparent and has no effect or coloration, fully reflecting the original sound of the TDA1541 chip without making any improvement or change to the sound quality output by the chip. This is also it has been repeatedly adopted.
