TS34119CS RLG

Overview

The TS34119CS RLG is a low power audio amplifier in an SOP-8 package. It operates from a supply voltage of +2V to +16V and drives speaker loads between 8Ω and 100Ω. The device provides differential outputs (VO1, VO2) with an open loop gain of 70dB and closed loop gain adjustable up to 46dB. Power supply current ranges from 2.7mA to 5.0mA depending on voltage, dropping to 65µA in disabled mode. It features a chip disable pin for muting or power down.

Feature Summary

• Provides differential speaker outputs to maximize swing at low voltages without coupling capacitors
• Includes a chip disable input for power conservation and signal muting
• Features adjustable closed-loop gain via external resistors for voice band applications
• Offers high power supply rejection through dedicated FC1 and FC2 pins

Applications

• Telephone speakerphones
• Battery-powered audio devices
• Line-powered audio circuits

Procurement Notes

Verify the part number suffix 'G' indicates halogen-free compliance as specified by Taiwan Semiconductor. Confirm the package type is SOP-8 and the packing quantity matches the standard reel size of 2,500 pieces. Ensure the application environment stays within the recommended operating temperature range of -20°C to +70°C for optimal performance.

Selection Notes

Select this component for designs requiring low quiescent current and operation at minimum supply voltages of 2.0V. It is suitable for applications needing differential output drive capabilities directly to speakers. Consider the thermal resistance of 180°C/W for surface mount packages when calculating power dissipation limits under varying ambient temperatures.

Part Context

This component belongs to the TS34119 series of low power audio amplifiers manufactured by Taiwan Semiconductor Corporation. It is designed primarily for telephone applications such as speakerphones. The device integrates two operational amplifiers to create a differential output stage, eliminating the need for bulky output coupling capacitors found in other amplifier classes.
