TPA3136AD2EVM: 10 W @ 8Ω, Class D, 8 ~ 14.4V in

Summary

The TPA3136AD2 EVM customer evaluation module demonstrates the TPA3136AD2 integrated circuit from Texas Instruments (TI). The TPA3136AD2 is a 10-W (per channel), efficient, stereo, digital-amplifier power stage for driving 2 bridge-tied speakers.

Features:

2 × 10 W/ch into 6-Ω loads at 10% THD+N from a 12-V supply
2 × 10 W/ch into 8-Ω loads at 10% THD+N from a 13-V supply
Up to 90% Efficient class-D operation (8 Ω) eliminates need for heat sinks
<0.05% THD+N at 1 W/4 Ω/1 kHz
Wide supply voltage range allows operation from 4.5 V (8 V for TPA3136AD2) to 14.4 V
Inductor-free operation
Enhanced EMI performance with spread spectrum
SpeakerGuard™ speaker protection includes power limiter and DC protection
Robust pin-to-pin, pin-to-ground, and pin-to-power short circuit protection and thermal protection
26-dB Fixed gain
Single-ended or differential analog inputs
Click and pop free startup
