TL3474ACD

Instrumentation, Op Amps, Buffer Amps Overview

The TL3474ACD is a quad high-slew-rate operational amplifier manufactured by Texas Instruments. It features four independent channels with rail-to-rail input and output capabilities, supporting single-supply operation from 4 V to 36 V or dual supplies of ±2 V to ±18 V. Key electrical specifications include a gain-bandwidth product of 4 MHz, a slew rate of 10 V/µs, and an input offset voltage of 3 mV. The device draws 3.5 mA of supply current and provides 27 mA of output current per channel. It operates within a temperature range of -40°C to +105°C and is housed in a 14-pin SOIC package.

Instrumentation, Op Amps, Buffer Amps Feature Summary

Instrumentation, Op Amps, Buffer Amps Applications

• Audio processing circuits
• Video buffering applications
• General-purpose analog signal conditioning

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'CD' against the manufacturer's official datasheet to confirm the exact package type (SOIC-14) and temperature grade (A-grade). Ensure compatibility with the required PCB footprint and soldering profile for surface-mount assembly. Cross-reference the ordering part number with the latest Texas Instruments documentation to avoid discrepancies in pinout or electrical characteristics.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when high-speed signal handling is required alongside full rail-to-rail swing capability. The 4 MHz bandwidth and 10 V/µs slew rate make it suitable for video and audio applications where distortion must be minimized. Consider the 3.5 mA quiescent current for power-sensitive designs compared to lower-power alternatives like the OPA347 series if speed is not critical.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the TL3474A family of high-performance operational amplifiers. It serves as a quad-channel variant designed for applications requiring multiple independent amplification stages. The 'A' designation typically indicates an extended or specific commercial temperature range, while 'CD' specifies the SOIC package and temperature grade.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Check for direct substitutes such as TL3474IDR or TL3474ACN, ensuring package compatibility (SOIC vs. PDIP) and matching electrical parameters. Verify that alternative quad op-amps maintain similar slew rates and rail-to-rail characteristics for functional equivalence.
