The TPA3112D1PWP from Texas Instruments is a 25-W efficient, Class-D audio power amplifier designed for driving bridge-tied speakers. It offers a wide supply voltage range from 8 to 26 V, enabling flexible power solutions.
Key electrical specifications include 25-W output power into an 8-Ω load at less than 0.1% THD+N from a 24-V supply, and 20-W into a 4-Ω load at 10% THD+N from a 12-V supply. The amplifier boasts 94% efficiency in Class-D operation into an 8-Ω load, minimizing heat dissipation and eliminating the need for heatsinks.
This device features filter-free operation and includes the SpeakerGuard™ speaker protection system, which incorporates an adjustable power limiter and DC detection. Advanced EMI suppression technology allows for the use of inexpensive ferrite bead filters while meeting EMC requirements. The amplifier also provides robust pin-to-pin short circuit protection and thermal protection with auto-recovery.
The TPA3112D1PWP is housed in a 28-pin HTSSOP package, facilitating easy board layout with its flow-through pin out. It operates within a temperature range of -40 to 85 °C and is supplied on a large tape and reel.
