INA1620RTWT

Overview

The INA1620RTWT is a high-fidelity audio operational amplifier manufactured by Texas Instruments. It features integrated thin-film resistors and EMI filtering capabilities. The device operates within a temperature range of -40°C to 125°C and is housed in a 24-pin WQFN (RTW) package. Key electrical characteristics include an ultra-low noise specification of 2.8 nV/√Hz at 1 kHz and integration with matched components typically at 0.004%. This component is designed for stereo Class-AB audio applications requiring high output current.

Feature Summary

• Integrated EMI filters for signal integrity
• Ultra-low noise performance suitable for audio fidelity
• Built-in matched thin-film resistors

Applications

• High-fidelity audio operational amplification
• Stereo Class-AB audio circuits
• Audio systems requiring EMI suppression

Procurement Notes

Verify the specific suffix RTWT against official Texas Instruments documentation to confirm the 24-WQFN package and tape-and-reel packaging configuration. Ensure compatibility with the required operating temperature range of -40°C to 125°C for your specific application environment before finalizing procurement.

Selection Notes

Select this component when designing audio circuits that demand low noise and high output current. The integrated EMI filtering and thin-film resistors reduce external component count. Verify that the 24-pin WQFN footprint fits your PCB layout constraints and thermal management requirements.

Part Context

This part belongs to the Texas Instruments audio operational amplifier family, specifically engineered for high-fidelity sound reproduction. It combines precision analog performance with integrated passive elements to simplify circuit design for professional and consumer audio equipment.

Replacement Considerations

Consult official substitution guides for equivalent dual-channel audio op-amps with similar noise profiles and WQFN packaging. Verify pinout compatibility and thermal characteristics before replacing.
