UA741CDT

Instrumentation, Op Amps, Buffer Amps Overview

The UA741CDT is a high-performance monolithic operational amplifier from the UA741 series, manufactured by STMicroelectronics. It features a single channel housed in an 8-pin SOIC surface-mount package. The device operates within a supply voltage range of 5 V to 40 V and supports a maximum output current of 25 mA. Key electrical parameters include a gain-bandwidth product of 1 MHz, a slew rate of 0.5 V/µs, and an input bias current of 70 nA. The input offset voltage is specified at 6 mV. It functions within a commercial temperature range of 0°C to 70°C.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Internal frequency compensation network ensures stability in closed-loop circuits without external components.
• Short-circuit protection safeguards the output stage against overload conditions.
• Wide common-mode and differential input voltage ranges facilitate versatile analog applications.
• No latch-up characteristic makes the amplifier suitable for voltage-follower configurations.

• Integrator circuits
• Summing amplifiers
• General feedback applications

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'CDT' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 8-SOIC footprint dimensions align with the target PCB design constraints. Ensure the component meets RoHS3 compliance standards if mandated by the end-product regulations. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before finalizing procurement orders.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a general-purpose, internally compensated operational amplifier is required for standard analog signal processing tasks. The UA741CDT is appropriate for designs needing moderate bandwidth and high gain with a wide operating voltage range. Consider the 8-SOIC package for surface-mount assembly requirements. Evaluate the 0.5 V/µs slew rate and 1 MHz gain-bandwidth product against the specific signal frequency and amplitude requirements of the application circuit to ensure adequate performance margins.

Instrumentation, Op Amps, Buffer Amps Part Context

The UA741CDT belongs to the legacy UA741 family, which established the standard for general-purpose operational amplifiers. This series is characterized by its robust construction on a single silicon chip and compatibility with the pin configuration of earlier models like the UA709. The CD variant denotes the industrial/commercial grade temperature range and SOIC packaging, distinguishing it from military or ceramic packages found in other UA741 derivatives.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The UA741CDT shares the same pin configuration as the UA709, allowing for potential physical interchangeability in existing layouts where electrical specifications permit. Verify that any substitute component maintains the internal compensation characteristics to avoid oscillation in closed-loop configurations.
