OPA2134PA Texas Instruments Dual Audio Operational Amplifier PDIP-8

The OPA2134PA is a high-performance dual audio operational amplifier from Texas Instruments, designed for applications requiring low noise, low distortion and high signal quality.

Part of the SoundPlus™ family, this integrated circuit uses a FET input stage, delivering excellent performance in audio applications, especially signal circuits, preamplifiers, active filters, line drivers, line receivers, mixers, audio processors and Hi-Fi equipment.

With a wide supply range of 5V to 36V or ±2.5V to ±18V, 8MHz bandwidth, 20V/µs slew rate and typical input noise of 8nV/√Hz, the OPA2134PA is an excellent choice for repair, maintenance, upgrades and analog audio circuit construction.

The PDIP-8 package makes it easy to use on printed circuit boards, prototyping boards and when replacing parts in existing equipment using traditional THT mounting.

Important note

Before use, always confirm the supply voltage, pinout, package, bandwidth, current consumption, thermal conditions and compatibility with the original circuit. The OPA2134PA is an audio signal operational amplifier, not a power amplifier for direct speaker connection. The final selection must match the real circuit conditions, including voltage, impedance, frequency, gain, load and available board space.
