概述

Description

TPA2016D2RTJR is Texas Instruments’ dual-channel, filterless (no external output filter) Class-D audio amplifier. It drives two speaker channels from a single supply (typical 2.5–5.5 V) and is designed for compact, battery-powered devices. Because it is filterless, you can directly connect to 4–8 Ω loudspeakers, saving BOM cost and board space. Key features include MUTE/ENABLE control, thermal shutdown, current limit, undervoltage protection, and pop-noise suppression. The outputs are Bridge-Tied Load (BTL) for increased speaker drive and efficiency, with differential inputs to minimize noise. The RTJR suffix indicates Tape-and-Reel packaging. Typical applications are portable electronics such as mobile devices, handheld toys, tablets, and small speakers. For precise electrical specs (output power per channel, THD, quiescent current, recommended load, supply rails), consult the TI datasheet for TPA2016D2 and the RTJR packaging variant.

Features

Here are the key features of the TPA2016D2RTJR (filterless stereo Class-D audio power amplifier):
- Stereo, filterless Class-D audio power amplifier (two channels) with differential outputs (BTL).
- No output filter required; simplifies design and reduces external components.
- About 1 W per channel into 8 Ω at 5 V (approx), with up to ~2 W total output capability.
- Spread-Spectrum modulation to minimize EMI.
- Soft-start/pop-free power-up and power-down.
- Thermal shutdown and overcurrent/short-circuit protection; undervoltage protection.
- Single-supply operation within a broad range (typical 2.7 V–5.5 V).
- Flexible input options (differential or single-ended with internal biasing).
- Efficient operation with low quiescent current.
- Package: 8-pin VSSOP (D2) with RTJR suffix.
Note: Exact output power depends on supply voltage and load; verify in the datasheet for your specific operating conditions.

Package

8-pin VSSOP (Very Small Outline Package).

Pinout

- Pin count: 16 pins (16-pin package).
- Function: Dual-channel, filterless (PWM) Class-D audio power amplifier. Provides differential speaker outputs (L+/L− and R+/R−) to drive two speakers from a single supply, with per-channel inputs (and control pins such as shutdown/mute) plus VDD and ground.

Manufacturer

- Manufacturer: Texas Instruments (TI).
