TS34119CS

Overview

The TS34119CS is a low-power audio amplifier manufactured by Taiwan Semiconductor Corporation. It features two channels and operates in Class-A configuration with differential output. The device delivers an output power of 250 mW into a 32 Ohm load, maintaining a total harmonic distortion plus noise of 0.6%. It functions within a supply voltage range of 2 V to 16 V and draws a working supply current of 65 uA. Key electrical parameters include a gain of 80 dB and a gain-bandwidth product of 1.5 MHz. The input bias current is specified at -100 nA. The component is housed in an SOP-8 package for surface mount installation and supports operation temperatures from -20 C to +70 C.

Feature Summary

• Provides differential output capability for stereo audio applications
• Certified for automotive reliability under AEC-Q101 standards
• Designed for ultra-low quiescent current consumption

Applications

• Automotive audio systems requiring AEC-Q101 compliance
• Low-power portable electronic devices
• Battery-operated consumer electronics

Procurement Notes

Verify the specific suffix designation (e.g., RLG) against the manufacturer's official datasheet to ensure correct packaging and tape-and-reel specifications. Confirm that the SOP-8 package dimensions match the target PCB footprint. Ensure the selected variant meets the required operating temperature range and humidity sensitivity classifications for the intended assembly process.

Selection Notes

Select this component when a dual-channel Class-A amplifier with differential output is required for low-voltage applications. The 65 uA supply current makes it suitable for battery-powered designs where power efficiency is critical. Verify that the 1.5 MHz gain-bandwidth product and 80 dB gain meet the signal processing requirements of the specific audio circuit topology.
