Frequently Asked Questions
What CMRR does the SM73308MGX/NOPB achieve and why does that matter for sensor circuits?
The SM73308MGX/NOPB achieves a typical common-mode rejection ratio of 90 dB and a minimum of 80 dB, which means it can reject common-mode noise on the input by a factor of over 30,000, making it suitable for differential sensor interfaces in electrically noisy industrial and medical environments.
How does the rail-to-rail output of the SM73308MGX/NOPB benefit low-voltage 3.3 V designs?
The rail-to-rail output swings to within a few millivolts of both supply rails, allowing the SM73308MGX/NOPB to deliver the full output signal swing of a 3.3 V supply, maximizing ADC input utilization and improving measurement resolution compared to non-RRO op-amps that lose 1 V or more of headroom.
For high-impedance sensor inputs, how low is the input bias current of the SM73308MGX/NOPB?
The SM73308MGX/NOPB specifies a maximum input bias current of 0.25 µA at 25°C, with a typical input offset current below 0.1 µA, minimizing measurement error when interfacing with high-impedance sensors such as pH electrodes, photodiodes, and piezoelectric transducers.
Can the SM73308MGX/NOPB replace a larger SOIC op-amp when board space is constrained in medical wearables?
Yes, the SM73308MGX/NOPB is housed in a compact 5-pin SOT-23 package measuring approximately 1.6 mm × 2.9 mm, making it a drop-in replacement strategy for SOIC-8 packaged op-amps in medical wearables and portable diagnostics where PCB area is at a premium.
