TS2007IQT

Overview

The TS2007IQT is a Class D audio power amplifier in a DFN8 3x3 mm package. It operates from 2.4 V to 5.5 V, delivering 1.4 W into 8 Ω at 5 V or 0.45 W at 3.0 V with 1% THD+N. The device features selectable fixed gains of 6 dB or 12 dB via the GS pin and includes a standby mode reducing current to 10 nA typ. Key electrical parameters include an efficiency of 88% typ, SNR of 94 dB typ, PSRR of 63 dB typ at 217 Hz, and a PWM base frequency of 280 kHz.

Feature Summary

• Filter-free architecture enabling simplified PCB design without external LC filters
• Configurable gain selection between 6 dB and 12 dB using a logic signal on the GS pin
• Low pop and click noise circuitry for quiet startup and shutdown operations
• Active low standby function significantly reduces current consumption

Applications

• Cellular phones
• PDAs
• Notebook PCs

Procurement Notes

Verify the specific ordering suffix 'IQT' against official STMicroelectronics documentation to confirm package type and temperature range specifications. Ensure compatibility with the required supply voltage range of 2.4 V to 5.5 V and confirm that the DFN8 3x3 mm footprint matches the target PCB layout constraints.

Selection Notes

Select this component for applications requiring high efficiency and minimal external components. The differential input configuration simplifies interfacing with audio DACs. Consider the thermal resistance characteristics when designing for enclosed spaces, as the device relies on PCB heat dissipation. Verify that the load impedance meets the minimum requirement of 3.2 Ω for stable operation.

Part Context

This part belongs to the TS2007 family of filter-free Class D amplifiers. It is designed for portable consumer electronics where space and power efficiency are critical. The DFN8 package provides a compact solution suitable for modern mobile devices. The device integrates protection features such as thermal shutdown and latch-up immunity.
