What are the key features of OPA350PAG4?

38 MHz gain-bandwidth product with rail-to-rail output swing enables high-speed signal processing from a single 2.5 V to 5.5 V supply
90 dB typical CMRR and 1000 µV maximum input offset voltage deliver precision performance in single-ended and differential sensor conditioning circuits
Single-supply operation from 2.5 V to 5.5 V with rail-to-rail output maximizes dynamic range in battery-powered and 3.3 V logic-interfaced designs

What is OPA350PAG4 used for?

The OPA350PAG4 is well suited for active filter stages, ADC input buffers, and sensor signal conditioning in portable instruments and battery-operated medical devices powered from a single 3.3 V or 5 V rail. Its 38 MHz gain-bandwidth product supports anti-aliasing filters and video signal processing applications requiring flat response up to several MHz. The 8-pin DIP package makes it convenient for prototyping and low-volume production where through-hole soldering is preferred.

Frequently Asked Questions

What gain-bandwidth product does OPA350PAG4 deliver, and at which supply voltage is it specified?

The OPA350PAG4 achieves a gain-bandwidth product of 38 MHz, typically specified at a 5 V single supply. This bandwidth supports signal amplification up to several MHz in ADC input buffer, active filter, and data acquisition front-end circuits powered from 2.5 V to 5.5 V rails.

For a single 3.3 V sensor conditioning circuit, how does the OPA350PAG4 compare to a dual-supply op-amp in terms of output swing?

Operating from a 3.3 V single supply, the OPA350PAG4 delivers a rail-to-rail output swing typically within 10 mV of each supply rail, effectively covering nearly the full 3.3 V output range. A conventional dual-supply op-amp would need ±1.65 V rails and would lose 100 mV to 300 mV headroom on each rail, reducing usable output swing by up to 18% compared to OPA350's rail-to-rail architecture.

How does the 74 dB minimum CMRR of OPA350PAG4 benefit designs interfacing with resistive bridge sensors?

A 74 dB minimum CMRR (90 dB typical) means the OPA350PAG4 rejects common-mode noise by at least a factor of 5000:1, suppressing 50 Hz or 60 Hz power-line interference that often couples into Wheatstone bridge outputs. For a 0.8 µA maximum bias current and 1000 µV maximum offset, this translates to less than 0.024% full-scale error in a 4.096 V reference system with 10 kΩ source impedances.
