TS419ID

Overview

The TS419ID is a monaural audio power amplifier from STMicroelectronics, operating within a supply voltage range of 2V to 5.5V. It drives 16 or 32-ohm loads in BTL mode, delivering up to 367mW at 5V with 10% THD+N and 295mW at 1% THD+N. The device features an active-high standby mode that reduces current consumption to 10nA typical. Key electrical parameters include a maximum supply current of 2.5mA, a signal-to-noise ratio of 95dB(A) at 5V, and a power supply rejection ratio of 56dB at 1kHz. It operates across a temperature range of -40°C to +85°C.

Feature Summary

BTL configuration eliminates bulky output capacitors
Active-high standby mode for ultra-low power consumption
Integrated ON/OFF click reduction circuitry
Short-circuit limitation protection

Applications

16/32 ohms earpiece or receiver speaker driver
Mobile and cordless phones (analog / digital)
PDAs & computers
Portable appliances

Procurement Notes

Verify the specific package suffix against the datasheet ordering codes. The 'I' indicates industrial temperature range (-40°C to +85°C). Confirm if the 'D' suffix for SO8 tube packaging or 'DT' for tape and reel is required for the design. Ensure the active-high standby logic matches the system control interface.

Selection Notes

Select this component for applications requiring low-voltage operation down to 2V. The fixed gain versions are available if external resistors are undesirable. Consider the MiniSO8 or DFN packages for space-constrained designs. Verify thermal dissipation requirements based on the load resistance and ambient temperature conditions.

Part Context

This part belongs to the TS419/TS421 family of Class-AB mono amplifiers. The TS421 variant offers an active-low standby mode instead of active-high. Both share identical electrical characteristics and pinouts, differing only in standby logic. They are designed for portable electronics where battery life and sound quality are critical.
