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.
