UA748CN

Instrumentation, Op Amps, Buffer Amps Overview

The UA748CN is a general-purpose operational amplifier manufactured by STMicroelectronics. It features a single silicon chip design with close match and tight thermal coupling for low offsets and temperature drift. The device operates from ±5V to ±15V dual supplies, consuming 50mW at ±15V. Key electrical characteristics include a maximum input offset voltage of 3mV over temperature and frequency compensation via a single 30pF capacitor. It offers continuous short-circuit protection and can function as a comparator with differential inputs up to ±30V without latch-up when the common-mode range is exceeded.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the package type matches the required SOIC-8 or DIP-8 configuration for your specific PCB layout needs. Confirm that the operating temperature range aligns with your application environment, as industrial variants may differ from commercial grades. Ensure supply voltage limits are respected to maintain device integrity and avoid exceeding the specified ±15V maximum rating during system operation.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for applications requiring a robust, general-purpose op-amp with inherent short-circuit protection. It is suitable where moderate precision is acceptable, given the 3mV max input offset voltage. Consider its compatibility with standard ±5V to ±15V power rails. Evaluate if the single-chip thermal coupling benefits outweigh the need for higher-speed alternatives in your specific circuit design constraints.
