Quad CMOS op-amp for precision, high-impedance signal chains
The four amplifiers share a single 14-SOIC package, making it a space-efficient choice for multi-channel sensor conditioning, photodiode amplifiers, data acquisition front-ends, and battery-powered instrumentation where every microamp of bias current matters.
Slew rate and bandwidth — what they mean for signal fidelity
The 1.3 V/µs slew rate and 1.5 MHz gain-bandwidth product define the large-signal and small-signal speed. For a 5 V peak-to-peak output step, the slew rate limits the full-swing risetime to about 3.8 µs. That is fast enough for 10 kHz sine waves at full amplitude and for multiplexed data-acquisition channels scanning at tens of kilohertz. If your application requires faster settling — say, driving a 100 kHz signal at 10 V p-p — a higher-slew-rate part like the OPA4374 (5 V/µs) may be a better fit. The 1.5 MHz GBW also means closed-loop gain up to 100 at 15 kHz is stable with typical compensation.
Package and temperature grade for industrial environments
The junction temperature rating (TJ) means the die temperature — not just ambient — is the limit; in a still-air environment at 85°C ambient, the 2.6 mA supply current per channel (10.4 mA total) produces negligible self-heating, so the full temperature range is usable without derating.
