RC4558: Automotive device recommend

Part Number: RC4558
Other Parts Discussed in Thread: RC4580-Q1, OPA2992-Q1, TLV9362-Q1, RC4580

Hi team,

Could you please kindly help recommend an automotive audio buffer device like RC4558?

Customer is using DSP output RCA signal about 2V,they need to use a buffer to get a 3.5V signal.



  • Hey Brian,

    The closest device to the RC4558 in automotive is the RC4580-Q1. Here is a comparison table between the two devices, as well as the OPA2992-Q1 and TLV9362-Q1. These last two devices are CMOS but offer improved performance over the RC4558 in many specs.

    Please note. The drift of the RC4558 and RC4580 is not 0, it is not specified in the datasheet.
