Product details

Class AB stereo headphone driver for portable and industrial audio

The Texas Instruments TPA102DGN is a Class AB stereo headphone amplifier delivering 70 mW per channel into 8 Ω loads. It operates from a single 2.5 V to 5.5 V supply.

70 mW into 8 Ω — what that means for headphone selection

70 mW per channel into 8 Ω drives most portable headphones. High-impedance studio monitors will not reach useful volume.

Protection features that simplify the BOM

Short-circuit and thermal protection are integrated, so no external current-limiting resistor or thermal cutoff is needed. The shutdown pin allows the host MCU to gate the amplifier when no audio is present, cutting quiescent draw to near zero — a useful power-save for battery-operated designs. Pop-reduction circuitry (depop feature) suppresses turn-on/turn-off clicks that otherwise annoy the user and require external mute circuits.

Sourcing and lifecycle — active production, no LTB risk

The TPA102DGN carries an Active product status with ROHS3 compliance. No last-time-buy or end-of-life notices are published. For new designs or production replenishment, this part is sourced through independent distribution and quoted to order — availability and current pricing are confirmed at quote time.

Frequently asked questions

What is the output power of TPA102DGN per channel?

The TPA102DGN delivers 70 mW per channel into an 8 Ω load, making it suitable for low-impedance headphones and portable speakers.

Can TPA102DGN be used as a replacement for TPA102?

The TPA102DGN is a specific package variant (8-HVSSOP exposed pad) of the TPA102 family. Verify pin compatibility and thermal pad connection against your PCB layout before substituting.
