概述

Description

TPA7836B-QP is a Texas Instruments dual-channel audio power amplifier for compact consumer electronics. It provides two amplifier channels in a single device, designed for efficient speaker drive with built-in protection and simple control.
Key points
- Dual-channel audio power amplifier suitable for small devices (TVs, set-top boxes, portable speakers, embedded audio).
- Built-in protections (short-circuit/thermal), and features like click/pop suppression and a mute/enable control.
- QP suffix indicates a RoHS-compliant, lead-free package option.
- Intended for single-supply operation with straightforward two-channel input/output connections and recommended decoupling per the datasheet.
How to use
- Connect the supply, feed each channel with its input, and connect outputs to speakers per the recommended layout.
- Use the enable/mute control to achieve quiet start-up.
- For exact electrical specs, pinout, package details, and layout guidelines, consult the official TPA7836B-QP datasheet.

Features

I don’t have the exact datasheet here. Here are typical features you’d expect on a dual low‑voltage audio amplifier like TPA7836B‑QP (verify with the official sheet):
- Dual-channel audio power amplifier for small loudspeakers
- Wide supply range (approx 2.5–5.5 V common)
- Protection: overcurrent/short‑circuit, thermal shutdown, undervoltage
- Pop-free turn-on/turn-off with mute or standby options
- Low quiescent current and efficient operation
- Capability to drive 4–8 Ω loads
- Small package (QP/8‑pin package variants) suitable for compact boards
- RoHS compliant
For exact electrical specs (output power per channel, THD, gain range, pinout, and conditions), please share the vendor (TI/Toshiba/etc.) or a datasheet link.

Package

QFN (Quad Flat No-lead) package with an exposed pad. The “-QP” suffix indicates TI’s QFN package.

Pinout

- Pin count: 28 pins (in automotive-grade -QP package variants).
- Function: Dual audio power amplifier (Class-D) with two amplification channels (left/right) and differential inputs/outputs; includes power supply (PVDD/VDD) and ground, plus control pins such as SHDN and MUTE/ENABLE (package varies).

Manufacturer

- Manufacturer: Texas Instruments (TI).
- What kind of company: American multinational technology company that designs and manufactures semiconductors and integrated circuits (notably analog, power management, and embedded processing).

Application

TPA7836B-QP is a compact stereo audio power amplifier. Typical applications include low-power consumer electronics that require built-in amplification: portable Bluetooth speakers and docking stations, mobile devices (phones, tablets, GPS), mini soundbars and multimedia receivers, toys and gadgets with speakers, automotive accessories, and general alarm/notification devices.
