What are the key features of OPA2330AIDGKTG4?
- Zero-drift auto-zero architecture holds input offset voltage below 50 µV across the full -40°C to +125°C temperature range, eliminating offset calibration in precision measurement designs
- Ultra-low 35 µA quiescent current per channel enables week-long battery life in portable sensor nodes and wearable medical devices
- 1.8 V minimum supply voltage with rail-to-rail output swing suits single-cell Li-ion and energy-harvesting systems where headroom is limited
- 115 dB typical CMRR and 100 dB minimum PSRR reject supply noise and common-mode interference in sensor bridge and thermocouple amplifier circuits
What is OPA2330AIDGKTG4 used for?
The OPA2330AIDGKTG4 is ideal for precision sensor conditioning in portable medical devices, such as glucose monitors and pulse-oximeters, where its 50 µV maximum offset and 35 µA supply current per channel allow accurate signal amplification on a single 1.8 V to 5.5 V supply for extended battery life. Its zero-drift topology suits instrumentation-grade thermocouple and bridge amplifiers in industrial process control, eliminating periodic offset calibration. The dual-channel MSOP-8 package also makes it attractive for compact data-acquisition front-ends in wearables and IoT sensor nodes that require two independent precision signal paths.

Frequently Asked Questions
How low is the input offset voltage of the OPA2330AIDGKTG4 across its operating temperature range?
The OPA2330AIDGKTG4 guarantees a maximum input offset voltage of 50 µV across the full -40°C to +125°C operating range, thanks to its auto-zero (chopper-stabilized) architecture. Typical offset is closer to 5 µV at 25°C. This near-zero drift eliminates the need for system-level offset calibration in precision thermocouple amplifiers, bridge sensors, and medical measurement circuits.
For a wearable biosensor running on a 3.6 V lithium coin cell, what quiescent current does the OPA2330AIDGKTG4 draw?
Each channel of the OPA2330AIDGKTG4 draws only 35 µA of quiescent current at 3.3 V supply, so both channels together consume approximately 70 µA. On a 220 mAh CR2032 coin cell this would allow over 3,000 hours of continuous operation from the op amp alone, making it an excellent fit for always-on biosensor signal conditioning in wearable health monitors.
When should a designer choose the OPA2330 over the OPA333 for a single-supply bridge measurement application?
The OPA2330AIDGKTG4 is a dual-channel version sharing the same zero-drift core as the single-channel OPA333. Choose OPA2330 when the circuit requires 2 independent precision amplifier stages — for example, a differential bridge amplifier followed by a low-pass filter — within a single MSOP-8 footprint, saving PCB area versus two OPA333 packages. Both guarantee 50 µV max offset and 35 µA per channel, so the dual variant lowers cost and board space in two-channel designs.
What is the gain-bandwidth product of the OPA2330AIDGKTG4, and does it limit use in audio-frequency sensor designs?
The OPA2330AIDGKTG4 has a gain-bandwidth product of 350 kHz, which is sufficient for DC to audio-frequency sensor conditioning up to approximately 3.5 kHz at a closed-loop gain of 100. For sensor applications such as strain-gauge amplifiers, RTD interfaces, and heart-rate monitors operating below 1 kHz, the 350 kHz GBP provides more than adequate bandwidth; for wider-bandwidth needs above 10 kHz at high gain, a faster op amp such as the OPA320 (20 MHz GBP) would be more appropriate.
