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−).
