Dual CMOS op-amp for micropower signal chains
Each channel draws 26 µA quiescent current while delivering rail-to-rail output swing and a gain-bandwidth product of 100 kHz. The CMOS input stage keeps input bias current at 0.002 pA, making it suitable for high-impedance sensor interfaces such as photodiode amplifiers, pH probe buffers, and electrochemical sensor front-ends where the source cannot tolerate loading. The supply span covers 4.5 V to 15.5 V, so it runs from a single 5 V rail or dual ±2.25 V to ±7.75 V supplies.
100 kHz gain bandwidth — intentional bandwidth limiting
The 100 kHz gain-bandwidth product and 0.02 V/µs slew rate are not limitations — they are design choices that keep the amplifier stable at low supply current. At 26 µA per amplifier, the internal compensation capacitor dominates the frequency response, so the part does not oscillate even with capacitive loads up to several hundred picofarads. For a 10 kHz low-pass filter or a DC-level shift stage, the bandwidth is adequate; for a 100 kHz PWM buffer the phase shift at the switching frequency will be significant. If the signal chain needs faster settling, the TLV9362IDDFR offers 10.6 MHz GBW at 2.6 mA supply — a different power-speed trade-off.
Industrial temperature range and operating environment
Outdoor telecom enclosures, factory-floor sensor transmitters, and under-hood electronics that stay below 85°C ambient are within the operating window.
Active lifecycle — no near-term obsolescence risk
The NOPB suffix confirms a lead-free, RoHS-compliant finish — no special handling beyond normal MSL precautions.
