OPA627X2 turn dual op amp finished ( Germany WBT-0820 silver soldering ) For hifi amplifier A3-013 | Электроника

OPA627X2 to double op/amp finished product wbt-0820   The finished product contains 2 pieces of 627, which can directly replace the operational amplifier of NE5532 and 2604 as an upgrade. This is the highest operational amplifier of BB company, with excellent high and low extension   When welding, we all choose the IC pairing number of the same batch number for welding. We don't need to worry about any imbalance Germany WBT-0820 silver tin identification of the most basic method: very bright solder spot far more than 1000 live   BB company has been soaring recently, so it has no choice but to raise the cost   The IC has two kinds of white words and laser. The white words are made in Malaysia, and the laser is made in Taiwan. There are also white words made in Taiwan.   Because the internal circuit is consistent, so its physical characteristics are also consistent, such as the working current is relatively large, working up than the general 5532,OPA275 to heat, in addition to the multi-meter measurement of the IC pin resistance value, the basic laser and black and white is consistent.   Top op-amp OPA627: BB company OPA627 is by far the most upscale op-amp, also using field effect tube input mode, sound warm and attractive, but its price is scary, used so expensive op-amp, whether can achieve the price also different opinions on performance, but hearing OPA627 enthusiasts are agree AD827, LT1057 cannot compare with them.
