Product details

What the 1 MHz GBW and 150 µA supply mean for your BOM

The Texas Instruments OPA344PA is a single-supply, general-purpose op-amp from the MicroAmplifier™ series, packaged in an 8-pin DIP for through-hole assembly. The 150 µA typical supply current keeps the power budget lean in battery-powered or loop-powered designs, while the rail-to-rail output stage maximizes dynamic range at low supply voltages. Input bias current is 0.2 pA typical, making it suitable for high-impedance sources like photodiodes or pH probes.

ROHS3 compliance is confirmed, so it passes European and global environmental requirements without an exemption.

Through-hole package and footprint fit

Housed in an 8-DIP (0.300", 7.62 mm pitch) with the supplier device package designated 8-PDIP, this part is designed for socketed or hand-soldered boards — prototyping, low-volume production, or retrofit where surface-mount reflow is impractical. The through-hole mounting type means the leads insert into plated through-holes on a standard 0.1" grid, compatible with breadboards and stripboard for initial validation.

Frequently asked questions

Can OPA344PA be used as a comparator?

The OPA344PA is a general-purpose op-amp, not a comparator. Its 0.8 V/µs slew rate and lack of internal hysteresis mean it will be slow and prone to oscillation when driven into saturation. For comparator duty, a dedicated comparator like the TLV3501 would be a better fit.
