What are the key features of INA134PAG4?
- Dual ±18V or single 8V-36V supply flexibility allows the INA134PAG4 to fit both split-rail audio systems and single-supply industrial designs
- Fixed-gain differential amplifier topology rejects common-mode noise on signal lines spanning long cable runs or noisy ground planes
- Industry-standard 8-pin PDIP package with plastic/epoxy construction simplifies prototyping and through-hole production assembly
What is INA134PAG4 used for?
The INA134PAG4 is widely used in professional audio equipment for balanced line receivers, microphone preamp input stages, and differential signal decoders that must reject common-mode noise on long cable runs. Its wide supply range makes it equally suitable for industrial process control interfaces, 4-20 mA loop receivers, and instrumentation front-ends where ground potential differences between transmitter and receiver reach several volts. Single-supply operation from 8V to 36V also enables use in battery-powered field instruments and portable audio measurement tools.

Frequently Asked Questions
What supply voltage options does the INA134PAG4 support, and how does single-supply operation compare to dual supply?
The INA134PAG4 accepts a dual supply from ±4V to ±18V or a single supply from 8V to 36V. Dual-supply operation centers the output at 0V, which is ideal for audio amplification of AC signals without DC offset. Single-supply operation shifts the operating point to mid-rail and suits industrial signal conditioning circuits powered from a single 12V or 24V rail without a negative supply generator.
How does the differential amplifier topology of INA134PAG4 help in balanced audio line receiver designs?
The INA134PAG4 amplifies the difference between its two input terminals while attenuating common-mode voltages by a high common-mode rejection ratio, typically 86 dB at 60 Hz. In a balanced audio link, any noise or hum induced equally on both wires of a cable pair appears as common-mode and is suppressed, while the 3-pin XLR signal differential is amplified cleanly, maintaining low distortion across the 20 Hz to 20 kHz audio band.
For an industrial 4-20 mA current loop receiver, how does INA134PAG4 handle ground potential differences of up to 10V between nodes?
In a 4-20 mA loop where the transmitter ground may float up to 10V above the receiver ground, the INA134PAG4's differential input rejects this common-mode offset as long as both inputs remain within the common-mode input range of the device. Operating from a ±18V supply, the device tolerates ground differences well within the ±18V input headroom, converting the differential current-sense voltage across a 100-ohm shunt resistor into a clean output voltage for the ADC.
