Frequently Asked Questions
What output power and distortion level does the TS4871ID deliver in a typical 8-ohm speaker circuit?
The TS4871ID delivers a nominal 1 W output power into an 8-ohm load with maximum total harmonic distortion (THD) of 1% at full power. This level is suitable for portable speaker applications in smartphones, tablets, and compact consumer audio products.
How does the TS4871ID's 2 MHz amplifier bandwidth benefit audio system designers?
The 2 MHz open-loop bandwidth of the TS4871ID ensures the closed-loop gain remains flat and phase margin stays adequate across the full 20 Hz to 20 kHz audio band. Designers gain more than 40 dB of loop gain at 20 kHz, reducing distortion and improving stability without external compensation components.
Which surface-mount package does the TS4871ID use and how small is its board footprint?
The TS4871ID uses an 8-pin SOIC (R-PDSO-G8) package with a body size of approximately 5 mm x 4 mm and 1.27 mm pin pitch, giving a compact footprint suitable for high-density consumer PCBs. The SOIC package is compatible with standard pick-and-place assembly and reflow soldering.
Can the TS4871ID replace a discrete Class-AB amplifier stage in a cost-sensitive IoT voice module?
Yes, the TS4871ID integrates a complete 1 W Class-AB amplifier with internal bias and protection in a single 8-pin SOIC package, eliminating 6 to 10 discrete components and reducing BOM cost. Its -40°C to +85°C operating range also covers the thermal requirements of industrial IoT voice-output applications.
