Overview
The TS419IST is a monaural audio power amplifier manufactured by STMicroelectronics, designed to drive 16 or 32 ohm earpiece or receiver speakers in Bridge-Tied Load (BTL) configuration. Operating from a supply voltage of 2V to 5.5V, it delivers up to 220mW continuous average power into 16 ohm loads with 0.2% THD+N. The device features an active high standby mode that reduces supply current to 10nA typical. It includes short-circuit limitation and ON/OFF click reduction circuitry.
Feature Summary
- Eliminates bulky output capacitors through BTL configuration
- Active high standby mode for ultra-low power consumption
- Integrated ON/OFF click reduction circuitry
- Externally configurable gain-setting resistors
Applications
- Driving 16 or 32 ohm earpieces
- Powering receiver speakers
- Low voltage portable audio devices
Procurement Notes
Verify the specific suffix IST against official STMicroelectronics documentation to confirm package type and temperature range. Ensure compatibility with system voltage requirements between 2V and 5.5V. Confirm availability status as product lifecycles may change. Cross-reference pinouts with the latest datasheet before integration.
Selection Notes
Select this component for applications requiring capacitor-less BTL operation in low voltage environments. Consider the 10nA standby current for battery-powered designs. Verify that the external gain-setting resistor configuration meets the desired audio output power levels within the specified THD+N limits.
Part Context
The TS419 belongs to STMicroelectronics' family of mono audio amplifiers, sharing functional similarities with the TS421, which differs primarily in standby mode polarity. These devices are engineered for compact audio solutions where space savings from removing output capacitors are critical.
FAQ
How does the standby mode function?
The TS419 features an active high standby mode that significantly reduces supply current to 10nA typical when activated.
What is the maximum output power capability?
It delivers up to 220mW per channel into 16 ohm loads with 0.2% THD+N from a 5V power supply.
