INA1651IPWR

Audio Special Purpose Overview

The INA1651IPWR is a high-voltage audio receiver from the SoundPlus series by Texas Instruments. It integrates a low-noise preamplifier and a power amplifier to drive loads directly from line-level inputs. The device operates on a single supply voltage ranging from 4.5V to 36V, or dual supplies of ±2.25V to ±18V. It features a fixed gain of 20dB and includes an integrated output filter for noise reduction. Packaged in a 14-TSSOP case, it supports surface mount installation and functions within a temperature range of -40°C to +125°C.

Audio Special Purpose Feature Summary

• Integrated audio receiver with low-noise preamp and power amp
• Fixed 20dB gain with integrated output filter
• Wide single-supply operation: 4.5V to 36V
• High-voltage capability up to 36V

Audio Special Purpose Applications

• Audio systems requiring direct line-to-speaker driving
• Automotive audio amplifiers
• Industrial audio interfaces

Audio Special Purpose Procurement Notes

Verify the package type matches the 14-TSSOP specification. Confirm the operating temperature range meets system requirements of -40°C to +125°C. Ensure the supply voltage stays within the 4.5V to 36V limit. Check for RoHS compliance status if required by local regulations.

Audio Special Purpose Selection Notes

Select this component when a combined preamplifier and power amplifier is needed for high-voltage audio applications. The fixed 20dB gain simplifies circuit design. Consider the 14-TSSOP package size for PCB layout constraints. Verify thermal management capabilities for the intended operating environment.

Audio Special Purpose Part Context

Part of the SoundPlus family, designed for robust audio performance. The IPWR suffix indicates a TSSOP-14 package in a tape and reel format. This model bridges the gap between line-level sources and speaker loads without external discrete components.

Audio Special Purpose Replacement Considerations

Check datasheet compatibility for pinout and electrical parameters before substituting. Verify that alternative devices support the same 36V maximum supply voltage and 20dB gain configuration.
