TPA6203A1GQVR

Overview

The TPA6203A1GQVR is a 1.25-W mono fully differential audio power amplifier designed for wireless handsets and PDAs. It operates from a single supply voltage ranging from 2.5 V to 5.5 V, delivering 1.25 W into an 8-Ω load at 5 V with 1% THD. The device features low quiescent current of 1.7 mA typical and shutdown current under 1 µA. It utilizes a space-saving 2 mm x 2 mm MicroStar Junior BGA package (GQV), requiring only five external components.

Feature Summary

• Fully differential architecture eliminates the need for input coupling capacitors and reduces RF rectification effects.
• High power supply rejection ratio improves immunity against noise in direct battery operation environments.
• Integrated thermal protection shuts down the device when junction temperature exceeds safe limits.
• Fast startup time minimizes audible pop noises during power transitions.

Applications

• Wireless cellular handsets
• Personal digital assistants (PDAs)
• Direct battery-powered audio systems

Procurement Notes

Verify that the GQV suffix corresponds to the standard MicroStar Junior package. Confirm the device meets Pb-free specifications if required by assembly processes. Ensure the order specifies the R suffix for taped and reeled packaging, as this variant is exclusively available in tape and reel format.

Selection Notes

Select this component for designs prioritizing minimal printed-circuit board area due to its compact 2 mm x 2 mm footprint. It is suitable for applications requiring high power supply rejection and reduced component count. Consider the fully differential output configuration for driving speakers directly without large blocking capacitors.

Part Context

This part belongs to the TPA6203A1 family of Class-AB audio amplifiers. The GQV designation identifies the specific leaded MicroStar Junior BGA package variant. Other variants include the ZQV option which is qualified for higher lead-free assembly temperatures.
