Overview
The TS489IQT is a dual-channel Class-AB stereo headphone amplifier manufactured by STMicroelectronics. It operates on a single supply voltage ranging from 2.2 V to 5.5 V with an operating supply current of 2 mA. The device delivers 130 mW of output power into a 16 Ohm load and features a gain-bandwidth product of 1.1 MHz. It includes pop-and-click noise suppression, input offset voltage of 20 mV, and functions within a temperature range of -40°C to +85°C. The component is housed in an 8-DFN (2x2 mm) package.
Feature Summary
- Dual-channel stereo audio amplification with integrated pop-and-click noise suppression for portable applications
- Class-AB topology supporting low-voltage single-supply operation down to 2.2 V
- Compact surface-mount packaging designed for space-constrained mobile devices
Applications
- Portable audio systems requiring stereo headphone output
- Mobile phones and smartphones
- Personal digital assistants (PDAs)
- MP3 players and portable media devices
Procurement Notes
Verify the specific suffix 'IQT' against the official STMicroelectronics datasheet to confirm pinout, thermal pad configuration, and RoHS compliance status. Confirm that the NRND status does not impact long-term availability requirements for your design lifecycle. Ensure the 8-DFN footprint matches your PCB layout constraints precisely.
Selection Notes
Select this component when a low-power, dual-channel solution is required for battery-operated devices. The 2 mA quiescent current supports extended battery life. Verify that the 130 mW output power meets the impedance requirements of the connected headphones. Consider the 8-DFN package size relative to available board space compared to alternative packages like MSOP.
Part Context
The TS489IQT belongs to the TS489 series of audio amplifiers from STMicroelectronics. This series targets the consumer electronics market, specifically focusing on low-voltage, high-efficiency performance for portable gadgets. It serves as a specialized solution for driving stereo headphones in compact form factors where power consumption and physical size are critical design parameters.
Replacement Considerations
Check for direct substitutes within the TS489 family or similar STMicroelectronics headphone amplifiers such as the TS488IQT or TS4909IQT. Verify compatibility regarding package dimensions, pin configurations, and electrical specifications before substitution.
