INA2134PA

Overview

The INA2134PA is a dual-channel audio differential line receiver manufactured by Texas Instruments. It integrates high-performance operational amplifiers with on-chip precision resistors to provide a fixed unity gain (0dB). The device operates within a supply voltage range of 8 V to 36 V and draws a typical operating current of 2.4 mA. It is housed in a 14-pin PDIP package and supports an extended industrial temperature range from -55°C to +125°C.

Feature Summary

• Integrates high-performance op amps with on-chip precision resistors for accurate signal reception
• Provides fixed unity gain configuration for direct differential-to-single-ended conversion
• Supports wide single-supply or split-supply voltage operation

Applications

• Audio transmitter and receiver systems
• Professional audio equipment line interfaces
• Differential audio signal conditioning circuits

Procurement Notes

Verify the specific suffix 'PA' corresponds to the 14-pin PDIP package variant when ordering. Confirm that the required operating temperature range includes the extended industrial limits if deployed in harsh environments. Ensure supply voltage constraints between 8 V and 36 V are strictly maintained during system design to prevent device damage.

Selection Notes

Select this component when a fixed-gain differential receiver is required for audio applications. It is suitable for designs needing integrated precision resistors to minimize external component count. Consider the PDIP package availability if through-hole mounting is necessary for the target PCB layout.

Part Context

This part belongs to the INA2134 family of audio differential line receivers. It shares functional similarities with the INA134 but offers enhanced performance specifications. The device is designed to replace discrete resistor networks in traditional differential receiver circuits, simplifying board space requirements while maintaining signal integrity.

Replacement Considerations

The INA2134UA/2K5 serves as a surface-mount alternative within the same family. Verify pin compatibility and package differences when substituting the PDIP version with SOIC variants.
