Product details

What this op-amp brings to the bench

Slew rate and bandwidth — the practical limits

The 4.6 V/µs slew rate means you can swing a 2 Vpp signal up to about 365 kHz before slew-induced distortion sets in. For small-signal work, the 12.5 MHz GBW gives you a closed-loop bandwidth of 12.5 MHz at unity gain, scaling inversely with noise gain. If you're building a 100 kHz active filter or a 1 MHz transimpedance amplifier, this part has the speed margin without burning excessive supply current.

The 500 µV max input offset voltage (typical is lower) is adequate for general-purpose signal conditioning; if you need sub-100 µV offset, a precision amplifier like the OPAx188 family would be a better fit.

Frequently asked questions

What is a suitable replacement or equivalent for OPA338UA?

The OPA4374AIPWT is a quad CMOS op-amp from TI with similar 6.5 MHz GBW and 5 V/µs slew rate, but in a TSSOP-14 package — not a pin-for-pin swap. For a single-channel replacement in the same 8-SOIC footprint, the TLV9351IDCKR offers 3.5 MHz GBW and 20 V/µs slew rate with a wider temperature range to 125°C. Neither is an exact drop-in; verify pin compatibility and supply range against your design.
