TPA6203A1ZQVR

Overview

The TPA6203A1ZQVR is a 1.25-W mono fully differential Class-AB 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 draws only 1.7 mA of typical quiescent supply current and features shutdown control consuming less than 10 μA. It utilizes a space-saving 2 mm x 2 mm MicroStar Junior BGA package (ZQV) and offers improved PSRR of 90 dB and CMRR to reduce RF rectification.

Feature Summary

• Fully differential design reduces RF rectification and eliminates the need for input coupling capacitors when driven by compatible sources.
• Optimized for direct battery operation with a wide supply voltage range from 2.5 V to 5.5 V.
• Low quiescent current consumption minimizes power drain in portable devices.
• Fast start-up time with minimal pop noise makes it suitable for applications requiring frequent power cycling.

Applications

• Wireless cellular handsets
• Personal Digital Assistants (PDAs)
• Battery-powered audio systems

Procurement Notes

Verify the specific ZQV package suffix indicates lead-free qualification for 260°C assembly processes. Confirm that the ordering code includes the 'R' suffix if taped and reeled packaging is required, as this package option is exclusively available in tape-and-reel format. Ensure compatibility with the -40°C to 85°C operating temperature range specified for commercial applications.

Selection Notes

Select this component for designs prioritizing minimal PCB area due to its compact 2x2 mm footprint. It is ideal for single-supply applications where low standby current is critical. Consider the fully differential architecture to simplify biasing from DACs without external coupling capacitors. Ensure resistor matching is maintained for optimal common-mode rejection performance.

Part Context

This device belongs to the TPA6203A1 family of mono audio amplifiers. It shares core electrical characteristics with other variants like the TPA6203A1GQVR, differing primarily in package type and lead-free qualification. The ZQV variant specifically provides the MicroStar Junior BGA form factor, distinguishing it from QFN or MSOP options within the same product line.

Replacement Considerations

TPA6203A1GQVR serves as a functional substitute with identical electrical specifications but utilizes the standard GQV MicroStar Junior package instead of the lead-free qualified ZQV variant.
