INA134PA

Overview

The INA134PA is a precision differential line receiver manufactured by Texas Instruments, designed for high-fidelity audio applications. It operates within a supply voltage range of 4 V to 18 V and functions reliably across an extended temperature range from -55°C to +155°C. The device utilizes an 8-pin SOIC surface-mount package and draws a typical supply current of 2.9 mA. As a single-channel component, it provides differential input to differential output conversion with bipolar logic functionality, ensuring accurate signal transmission in demanding environments.

Feature Summary

• Provides precise differential-to-differential signal conversion for balanced audio lines
• Operates reliably across an extended industrial temperature range down to -55°C
• Features low power consumption suitable for battery-operated or portable equipment

Applications

• Professional audio mixing consoles and preamplifiers
• Digital audio interface receivers
• Balanced microphone and line-level signal conditioning

Procurement Notes

Verify the specific package variant, as the INA134 series includes both through-hole (PDIP) and surface-mount (SOIC) options. Confirm that the required operating temperature range aligns with the component's specified limits. Ensure compatibility with existing board layouts when selecting between different package styles within the same functional family.

Selection Notes

Select this component when high common-mode rejection is required for balanced audio signals. Consider the extended temperature rating for harsh environments. Evaluate the supply voltage constraints against the system's power rails. Compare pinout compatibility if replacing legacy designs.

Part Context

The INA134 belongs to Texas Instruments' dedicated audio line receiver family, distinct from their general-purpose operational amplifiers like the OPA series. While sharing the '134' designation with other devices, it is specifically optimized for handling differential audio inputs rather than general signal amplification.
