TAS5720ATDAPRQ1

TAS5720ATDAPRQ1 is a Texas Instruments two-channel, filterless Class-D audio power amplifier. It accepts digital audio inputs (I2S/PCM) and directly drives two speaker outputs with high efficiency, using the speaker as the output filter to minimize external components. Key features include pop-free turn-on, protections (over/under-voltage, over-current, thermal shutdown, short-circuit), and diagnostic/status outputs. It’s suitable for compact consumer electronics and automotive audio where space and power are constrained, typically driving 4–8 Ω loads, with output power scaling with the supply. The suffix Q1 denotes packaging/assembly variant (e.g., RoHS-compliant, tape-and-reel).

Here are the typical features of the TAS5720ATDAPRQ1 (TI):
- Dual-channel, high-efficiency Class-D audio amplifier
- Bridge-Tied Load (BTL) outputs; direct speaker drive with no external output filter required
- Digital input interface (I2S/PCM) for feeding from a DAC; supports standard word lengths
- Spread-Spectrum modulation to reduce EMI
- Pop-free turn-on with soft-mute; configurable mute/standby control
- Integrated protections: undervoltage, overcurrent/short-circuit, overtemperature; fault reporting
- Output protection and current limiting on each channel
- Low quiescent current and reduced external component count
- Designed in a compact package suitable for portable/consumer electronics (TDAPRQ1 packaging)
Note: exact electrical ratings (output power per channel, supply range, supported sample rates) are specified in the TI datasheet for precise design values.

TAS5720ATDAPRQ1 is supplied in a 38‑pin HTSSOP (PWP) package. Function: a stereo Class‑D audio power amplifier (digital/PCM input with on‑chip PWM power stage). The pins include power rails (PVDD, AVDD, GND), differential PWM outputs (OUTA+/−, OUTB+/−), audio digital inputs/control (SDATA/BCLK/LRCLK or serial interface pins), mute/shutdown and reset, clock/FS pins, configuration/I2C or serial control pins, and fault/thermal detect pins. For the exact pin‑to‑function mapping and electrical characteristics, consult the TAS5720A datasheet from Texas Instruments.

The TAS5720ATDAPRQ1 is manufactured by Texas Instruments (TI). TI is an American multinational semiconductor company—an integrated device manufacturer (IDM) that designs, develops and manufactures analog, mixed-signal and digital ICs (including audio amplifiers, power management, microcontrollers and signal processors), headquartered in Dallas, Texas.

Application areas of TAS5720ATDAPRQ1:
- Automotive infotainment and premium car audio systems
- Home entertainment: soundbars, TVs, and AV receivers
- Computer and multimedia peripherals: PC speakers, docking stations
- Portable and wireless speakers and compact audio devices
- OEM/embedded electronics: compact two-channel amplifier modules in various consumer electronics

TAS5720ATDAPRQ1 is packaged in an HTSSOP (PowerPAD/exposed thermal pad) package; the RQ1 suffix indicates tape-and-reel. See the TI datasheet for pin count and mechanical drawings.
