TPA0253DGQG4

Overview

The TPA0253DGQG4 is a Class AB mono audio power amplifier with integrated headphone drive capability. It delivers 1 W of output power into an 8-Ω load and 85 mW per channel into two 32-Ω loads for stereo headphones. The device operates on a single supply voltage ranging from 2.5 V to 5.5 V, with a typical operating supply current of 3.2 mA. It utilizes a 10-MSOP-PowerPad surface-mount package compliant with RoHS standards.

Feature Summary

• Integrated bridge-tied-load (BTL) amplifier designed to drive low-impedance speakers down to 8 Ω.
• Dual functionality supporting both mono speaker output and independent stereo headphone channels.
• Includes internal depop circuitry to minimize audible switching noise during power-up and shutdown.

Applications

• Portable mono audio systems requiring direct speaker driving
• Handheld devices with integrated headphone jacks
• Low-power consumer electronics with single-supply constraints

Procurement Notes

Verify the DGQG4 suffix confirms the specific 10-MSOP-PowerPad package and lead-free compliance. Ensure the source document explicitly lists this part number as active status. Cross-reference the manufacturer's official ordering guide to confirm availability and exact pinout compatibility before procurement.

Selection Notes

Select this component when a single-supply solution is required for combined speaker and headphone outputs. It is suitable for applications needing 1 W into 8 Ω or dual 85 mW into 32 Ω loads. Consider the 10-MSOP-PowerPad package for thermal management in compact designs requiring Class AB linearity.

Part Context

This part belongs to Texas Instruments' TPA025x series of low-power audio amplifiers. The TPA0253 variant specifically integrates headphone drivers alongside the main BTL amplifier channel. It is designed for portable battery-operated devices where space and power efficiency are critical design constraints.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify functional equivalence with other TI TPA025x family members only if datasheet parameters match exactly.
