Overview
The TS488IST is a Class-AB stereo headphone amplifier manufactured by STMicroelectronics, designed for single-supply operation within a voltage range of 2.2 V to 5.5 V. It delivers up to 130 mW per channel into a 16 Ω load with a maximum Total Harmonic Distortion plus Noise (THD+N) of 0.3%. The device features a gain-bandwidth product of 1.1 MHz and operates with a typical supply current of 2 mA. It is housed in an 8-MiniSO package and supports a wide operating temperature range from -40°C to +85°C.
Feature Summary
- Integrated pop-and-click noise protection circuitry to eliminate audible transients during power-up and power-down sequences.
- Externally controlled standby mode that significantly reduces supply current consumption when the device is not in active use.
- Built-in short-circuit protection on output channels to safeguard the amplifier against load faults.
Applications
- Stereo headphone amplification in portable audio devices
- Mobile phone audio output stages
- MP3 players and digital media players
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for End-of-Life (NRND) designation before finalizing procurement plans. Ensure packaging specifications match production requirements.
Selection Notes
Select this component for applications requiring low-voltage stereo amplification with minimal external components. Consider the 8-MiniSO package for space-constrained designs. Verify that the required output power and THD specifications align with the system's audio quality standards.
Part Context
This part belongs to the TS488 series of audio amplifiers from STMicroelectronics. It is specifically engineered for battery-powered consumer electronics where power efficiency and audio fidelity are critical. The series includes variants with different packages and thermal characteristics.
Replacement Considerations
LM4809MM/NOPB and LM4809MMX/NOPB are documented as similar replacement options from Texas Instruments. Verify pin compatibility and electrical parameter alignment before substitution.
