OPA2134 VS TL072[Video]: What are the differences between them?

The OPA2134 is an audio-specific low-noise, ultra-low-distortion operational amplifier. A true FET input stage is integrated to give increased sound quality and speed for great audio performance. This, combined with its high output drive capability and excellent DC performance, qualifies it for a wide range of demanding applications. The OPA134 also has a wide output swing, within 1 V of the rails, giving it plenty of headroom and making it ideal for use in any audio circuit.

Single and dual versions are available in 8-pin DIP and SO-8 surface-mount packages in traditional configurations. The quad is available in 14-pin DIP and SO-14 surface-mount packaging. All are rated for temperatures ranging from –40°C to 85°C. A SPICE macro model is available for design analysis.

The TL072 devices are the next-generation successors of the TL07x (TL071, TL072, and TL074) devices. Low offset (1 mV, usual), high slew rate (20 V/s), and common-mode input to the positive supply make these devices an excellent choice for cost-conscious applications. The TL07xH devices can be utilized in the harshest and demanding applications thanks to their high ESD (1.5 kV, HBM), inbuilt EMI and RF filters, and operation from –40°C to 125°C.
