Product details

Dual CMOS op-amp for low-power signal chains

A 5.5 MHz gain-bandwidth product and 6 V/µs slew rate support audio-band filtering and moderate-speed sensor conditioning, while the 750 µA total supply current (both channels) keeps the thermal budget low in a through-hole 8-PDIP package.

Rail-to-rail output and supply range

The 150 µV typical input offset voltage and 0.2 pA input bias current suit precision DC-coupled stages where drift and loading must be minimised. Each channel can deliver 50 mA of output current, enough to drive a modest ADC reference buffer or a headphone load directly.

Confirm a second-source or a newer-package alternative before committing a production BOM to this order code.

Frequently asked questions

What is the replacement for OPA2340PAG4?

For a functional drop-in, look at the active OPA2340 family variants in SOIC-8 (surface-mount) — the through-hole PDIP version is end-of-life. Verify pin compatibility and electrical ratings against your specific supply and bandwidth requirements.

Does the OPA2340PAG4 have rail-to-rail output?

Yes, the output type is rail-to-rail, allowing the output to swing close to both supply rails. This is essential for single-supply circuits where headroom is limited.
