INA1650IPWR

Audio Special Purpose Overview

The INA1650IPWR is a SoundPlus high common-mode rejection line receiver manufactured by Texas Instruments. It operates on a single supply voltage ranging from 4.5 V to 36 V and draws a typical operating current of 9 mA. The device features a fixed gain of 20 V/V and provides a common-mode rejection ratio (CMRR) of 80 dB at 60 Hz. Designed for surface-mount installation, it is housed in a TSSOP-14 package. The component supports an input common-mode voltage range extending up to the positive supply rail, enabling direct connection to audio sources without external biasing networks.

Audio Special Purpose Feature Summary

• High Common-Mode Rejection: Achieves 80 dB CMRR at 60 Hz and 70 dB at 1 kHz.
• Wide Supply Voltage Range: Operates efficiently with supply voltages between 4.5 V and 36 V.
• Fixed Gain Configuration: Provides a precise internal gain of 20 V/V.
• Rail-to-Rail Input: Accepts input common-mode voltages up to the positive supply rail.

Audio Special Purpose Applications

• Professional audio equipment requiring balanced line reception.
• Automotive infotainment systems utilizing differential audio interfaces.
• Industrial control panels with analog audio monitoring capabilities.

Audio Special Purpose Procurement Notes

Verify the specific suffix 'IPWR' corresponds to the TSSOP-14 package and reel packaging format. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the procurement channel provides valid traceability for automotive or industrial qualification requirements if applicable.

Audio Special Purpose Selection Notes

Select this component when a fixed 20 V/V gain is required for differential audio signals. It is suitable for applications needing high common-mode rejection in noisy environments. Verify that the system supply voltage remains within the 4.5 V to 36 V operational limits. Consider thermal dissipation in the TSSOP-14 package if operating near maximum voltage ratings.

Audio Special Purpose Part Context

The INA1650 belongs to the SoundPlus family of audio interface components from Texas Instruments. This series focuses on robust signal reception in high-noise environments. The IPWR designation indicates the surface-mount TSSOP-14 variant packaged in reels for automated assembly processes.

Audio Special Purpose Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Evaluate alternative high-CMRR line receivers based on matching gain, supply voltage, and package constraints.
