概述
Description
TPA2033D1YZFR is a Texas Instruments two-channel, filterless Class-D audio amplifier. It delivers stereo audio from a single supply to 4–8 Ω loads with high efficiency and minimal external components, ideal for battery-powered devices.
Key points:
- Filterless (no external output filter required) BTL outputs for each channel.
- Wide supply range (roughly 2.7–5.5 V) with high efficiency.
- Built-in protections: undervoltage, overcurrent, thermal shutdown, plus short-circuit protection.
- Pop/mute features and quiet power-up to reduce switching noise.
- Small, RoHS-compliant package; “YZFR” indicates reel packaging.
Applications include mobile devices, Bluetooth speakers, portable audio accessories, and other consumer electronics where compact, efficient stereo amplification is desired.

Equivalent
There is no guaranteed exact drop-in from another vendor. Direct equivalents are other TI TPA2033D1 package variants. Near-equivalent substitutes (similar single-supply Class‑D audio amps) include TI TPA2005D1, PAM8403, Maxim MAX98306 and other small Class‑D parts — but verify pinout, gain, power, thermal and mute/standby behavior and PCB footprint before replacing.
Features
Here are the typical features of the TPA2033D1YZFR (TI):
- Dual 3-W Class-D audio amplifier (two channels)
- Filterless output architecture (no external LC filter required)
- Single-supply operation (typical around 5 V)
- High efficiency and low heat generation
- Pop-free startup/shutdown behavior
- Robust protection: overcurrent/short-circuit protection, thermal shutdown, undervoltage lockout
- Differential inputs (suitable for differential use; can be wired for single-ended)
- Compact MSOP-16 package with YZFR variant
Note: exact figures (power into a given load, voltage range, efficiency) come from the datasheet.
