Frequently Asked Questions
What is the supply voltage range for the OPA376AIDCKT?
The OPA376AIDCKT operates on a single supply voltage from 2.7V to 5.5V, or a dual supply of ±1.35V to ±2.75V. This wide range makes it compatible with 3.3V and 5V systems commonly used in embedded and portable designs.
What applications is the OPA376AIDCKT best suited for?
The OPA376AIDCKT excels in precision low-power applications such as medical instrumentation, portable sensor interfaces, photodiode amplifiers, and data acquisition systems. Its ultra-low 0.01pA input bias current and rail-to-rail I/O make it ideal for high-impedance signal sources and battery-powered devices.
What package type does the OPA376AIDCKT use and what are its dimensions?
The OPA376AIDCKT is housed in a 5-pin SC-70 (SOT-323) package, which measures approximately 2.0mm x 1.25mm. This compact footprint is ideal for space-constrained designs in wearables, medical devices, and handheld instruments.
Are there compatible alternative parts for the OPA376AIDCKT?
Compatible alternatives include the OPA376AIDBVT (SOT-23-5 package), OPA376AIDCKR (tape and reel variant of SC-70), and OPA340 series from Texas Instruments. Third-party equivalents with similar 5.5MHz bandwidth and rail-to-rail specs may also be considered, but verify pinout and electrical parameters before substitution.
