Part Number: OPA2188
Other Parts Discussed in Thread: RC4580,

Hi,

Currently our customer use the RC4580 but their are replacement to OPA2188 because to the attribute Low offset voltage.

Could you please advice to me checkt it below schematic. (Repacement only RC4580 to OPA2188)

    Hi Stewart,

    Your schematic didn't come through. The OPA2188 should drop into the RC4580 footprint and exceeds its dc electrical performances for most parameters. Do be aware though that the RC4580 has wider bandwidth and faster slewing rate than the OPA2188. Make sure that if the OPA2188 is selected for its dc characteristics that it meets the ac requirements as well.

    Hi Thomas,

    Thansk for your advice.
    You said, can't be used on the same circuit with replacement by RC4580 to OPA2188 and another(R,L and C value) device to not changed. Right??

    Our appliation is Hall Sensor.

    Thanks. Stewart
