Frequently Asked Questions
What is the CMRR of INA2134?
The INA2134 achieves 90dB common-mode rejection ratio, effectively eliminating ground loops, hum, and electromagnetic interference picked up on long audio cable runs. This makes it ideal for professional balanced audio interconnects.
How many channels does INA2134 have?
The INA2134 contains two independent differential receivers in one SOIC-8 package, perfect for stereo balanced audio applications. For single-channel needs, the INA134 is the single version in the same family.
Does INA2134 require external resistors?
No, the INA2134 includes precision laser-trimmed internal resistors that set unity gain and ensure high CMRR. No external components are needed for the signal path. This simplifies PCB layout and eliminates resistor matching concerns.
What supply voltage does INA2134 need?
The INA2134 operates on dual supply from ±2.25V to ±18V. For maximum audio headroom, ±15V supplies are recommended. At ±15V, output swing reaches ±12V, providing over 20dBu of headroom for professional audio levels.
