Frequently Asked Questions
What is the input offset voltage of the OPA2333AIDGKR?
The OPA2333AIDGKR features a maximum input offset voltage of 10 µV at 25°C, achieved through its zero-drift (chopper-stabilized) architecture. This makes it one of the most precise CMOS op-amps available, suitable for applications requiring sub-millivolt accuracy such as precision weigh scales and medical sensors.
What are the typical applications for the OPA2333AIDGKR?
The OPA2333AIDGKR is designed for high-precision signal conditioning applications including bridge sensor amplification, thermocouple and RTD measurement, medical instrumentation, portable data acquisition, and industrial process control. Its dual-channel design and low 350 µA supply current make it ideal for space-constrained and battery-powered systems.
What package does the OPA2333AIDGKR use and what is its pin count?
The OPA2333AIDGKR is housed in an 8-pin MSOP (VSSOP) small outline package (DGK suffix), measuring approximately 3 mm × 3 mm. This compact footprint is well-suited for high-density PCB layouts in portable and space-constrained applications.
What is a suitable replacement or alternative for the OPA2333AIDGKR?
Compatible alternatives to the OPA2333AIDGKR include the OPA2333AIDR (SOIC-8 package variant), the single-channel OPA333AIDBVR (SOT-23-5), and the OPA2335 series for applications requiring higher bandwidth. Ensure the replacement matches the supply voltage range (1.8 V to 5.5 V) and offset voltage specification for your design.
