Product details

What this quad audio op-amp brings to an automotive audio chain

The OPA1679QRUMRQ1 is a quad-channel audio op-amp from the Automotive, AEC-Q100 series. Its 16 MHz gain-bandwidth product and 9 V/µs slew rate handle 20 kHz audio bandwidth with margin for active filters.

AEC-Q100 qualification and temperature grade — the sourcing gate

It is rated for deployment in under-hood audio processing modules and cabin-zone amplifiers.

Each output can source or sink 50 mA.

Housed in a 16-WQFN with exposed pad (4 mm × 4 mm body), the part is surface-mount. The exposed pad ties to the negative supply rail (V−).

Frequently asked questions

Is the OPA1679QRUMRQ1 AEC-Q100 qualified?

Yes, it is part of the Automotive, AEC-Q100 series, which means it has passed the automotive-grade stress qualification for high-temperature operating life, temperature cycling, and ESD robustness.

Can the OPA1679QRUMRQ1 be used as a general-purpose op-amp?

Yes, while it is optimized for audio applications, its 16 MHz GBP, rail-to-rail output, and wide supply range make it suitable for general-purpose signal conditioning in automotive systems, such as sensor buffering, active filters, and level shifting, as long as the application benefits from the AEC-Q100 qualification.

What are alternatives or equivalents to the OPA1679QRUMRQ1?

The TLV9362IDDFR is a dual-channel general-purpose op-amp with 10.6 MHz GBP and 25 V/µs slew rate, but it lacks the audio-specific optimization and quad-channel count of the OPA1679QRUMRQ1. For a quad-channel replacement with similar bandwidth, the OPA4374AIPWT offers 6.5 MHz GBP and 5 V/µs slew rate in a CMOS rail-to-rail design, though it is not AEC-Q100 qualified.
