What are the key features of OPA2337EA/250?
- Dual CMOS op-amp with 10 pA (0.00001 µA) maximum input bias current and 90 dB typical CMRR, enabling high-accuracy signal conditioning for high-impedance sensor sources
- Single-supply CMOS architecture with rail-to-rail output swing suits 3 V and 5 V battery-powered designs without a negative supply rail
- MicroSIZE 8-pin SOT-23 package minimizes PCB footprint for wearable and space-constrained analog circuit designs
What is OPA2337EA/250 used for?
The OPA2337EA/250 is used in portable medical devices, handheld instruments, and battery-powered sensor interfaces where dual op-amp channels with sub-10 pA input bias current and 90 dB CMRR are needed to accurately amplify signals from high-impedance sensors such as pH electrodes or photodiodes. Its single-supply operation and 8-pin SOT-23 package make it equally suitable for compact industrial transmitter circuits and low-power data acquisition front ends running from 3 V to 5 V supplies.

Frequently Asked Questions
What input bias current does the OPA2337EA/250 specify, and why does it matter for high-impedance sensor interfaces?
The OPA2337EA/250 has a maximum input bias current of 0.00001 µA (10 pA), which is extremely low. For high-impedance sensors such as pH electrodes or photodiodes with source impedances in the megaohm range, a 10 pA bias current creates less than 10 µV of voltage error across a 1 MΩ source, preserving measurement accuracy without requiring external bias compensation networks.
How does the OPA2337EA/250 perform in terms of common-mode rejection, and where does this benefit a differential measurement circuit?
The OPA2337EA/250 achieves a minimum 74 dB and typical 90 dB common-mode rejection ratio (CMRR). In a differential measurement circuit such as a Wheatstone bridge amplifier or ECG front end, a 90 dB CMRR attenuates 50 Hz or 60 Hz mains interference and other common-mode noise by a factor of approximately 31,600, maintaining signal integrity without additional filtering stages.
Can the OPA2337EA/250 be used in a 3.3 V single-supply design, and what output voltage swing should engineers expect?
Yes, the OPA2337EA/250 is designed for single-supply operation and supports a 3.3 V supply rail. Its rail-to-rail output stage allows the output to swing to within a few millivolts of both supply rails, maximizing the usable output dynamic range in 3.3 V systems where a conventional op-amp would lose 0.5–1 V of headroom at each rail and reduce the effective signal range by over 30%.
