Product Details:
SSM2141 balanced to single ended circuit board, the core chip used in this circuit board SSM2141 is an integrated differential amplifier used to receive balanced line inputs, suitable for audio applications that require high immunity and optimal common mode rejection. The common mode rejection (CMR) performance of the chip (SSM2141) can typically reach 100 dB, while the implementation of an operational amplifier using four existing precision resistors can only achieve a CMR of 40 dB, which cannot meet the requirements of high-performance audio.
SSM2141 achieves low distortion performance by maintaining a high slew rate of 9.5 V/µ s and a high open-loop gain. Within the entire audio bandwidth, its distortion is less than 0.002%. SSM2141 can achieve equivalent transformer balance of audio signals without distortion or electromagnetic radiation (EMI) fields.
The decoupling of operational amplifier power supply has a significant impact on sound quality
Using ELNA audio specific capacitors and WIMA capacitors.
Using American DALE resistors.
