What are the key features of OPA330AIDCKRG4?
- Ultra-low 50 µV maximum input offset voltage ensures high DC accuracy in precision sensor signal conditioning and bridge amplifier applications
- 0.0005 µA maximum input bias current minimizes error in high-impedance signal sources such as pH electrodes, photodiodes, and piezoelectric sensors
- 115 dB typical common-mode rejection ratio provides excellent noise immunity in single-supply rail-to-rail output designs operating from 1.8 V to 5.5 V
What is OPA330AIDCKRG4 used for?
The OPA330AIDCKRG4 is optimized for precision sensor signal conditioning in portable medical devices, industrial transmitters, and data acquisition systems where DC accuracy and low offset are critical. Its 50 µV maximum offset voltage and 0.0005 µA bias current make it an excellent front-end amplifier for high-impedance sources such as thermistors, strain gauges, and electrochemical sensors. The compact SOT-23-5 package suits space-constrained portable instruments requiring low quiescent current and high common-mode rejection.

Frequently Asked Questions
How does OPA330AIDCKRG4 perform in precision DC measurement compared to general-purpose op-amps?
The OPA330AIDCKRG4 achieves a maximum input offset voltage of 50 µV and a minimum CMRR of 100 dB, which is significantly better than general-purpose CMOS op-amps that typically specify offsets of 1 mV to 5 mV. This makes it suitable for precision 16-bit or higher ADC front-ends in weigh-scale, pressure, and temperature measurement applications requiring less than 0.01% full-scale DC error.
What input bias current does OPA330AIDCKRG4 specify, and why does it matter for high-impedance sensor interfaces?
The OPA330AIDCKRG4 specifies a maximum input bias current of 0.0005 µA (500 pA) at 25 °C. For a 10 MΩ source impedance, this generates only 5 mV of additional offset error, negligible for most precision applications. This low bias current is critical when interfacing with pH electrodes, photodiodes, or piezoelectric transducers that present source impedances in the megaohm range.
Can OPA330AIDCKRG4 operate from a single 3.3 V supply in a microcontroller-based sensor node?
Yes, the OPA330AIDCKRG4 is designed for single-supply operation and its rail-to-rail output swing allows the output to approach within a few millivolts of both the positive and ground rails at 3.3 V supply. This maximizes the usable dynamic range when feeding a 12-bit or 16-bit ADC referenced to the same 3.3 V supply, which is a common requirement in battery-powered IoT sensor nodes.
In what package does OPA330AIDCKRG4 come, and how does it fit into a compact PCB layout?
The OPA330AIDCKRG4 is housed in a 5-pin SOT-23 (SC-74) package with a body size of approximately 2.9 mm x 1.6 mm, making it one of the smallest precision op-amp packages available. The G4 suffix indicates a tape-and-reel packaging of 3000 units, compatible with high-volume automated SMT assembly for portable medical and consumer devices where PCB space is at a premium.
