Overview
The TPA701DR is a Class-AB audio amplifier manufactured by Texas Instruments, designed for single-channel mono applications. It delivers an output power of 700 mW into an 8-ohm load with a total harmonic distortion plus noise of 0.55%. The device operates on a single power supply ranging from 2.5 V to 5.5 V and draws a typical operating current of 1.25 mA. It is housed in an 8-SOIC surface-mount package and functions within a temperature range of -40°C to +85°C.
Feature Summary
- Integrates short-circuit and thermal protection mechanisms to ensure operational reliability under fault conditions.
- Includes a shutdown feature that allows the device to be disabled to minimize power consumption when not in use.
Applications
- Portable audio devices requiring low-power amplification
- Single-speaker systems in consumer electronics
- Battery-operated audio equipment
Procurement Notes
Verify the specific ordering suffix to confirm the tape-and-reel packaging configuration, as variations exist within the product family. Ensure compatibility with the target PCB footprint for the SOIC-8 package. Confirm RoHS compliance status if required by project specifications. Cross-reference the manufacturer part number with distributor codes to avoid substitution errors during procurement.
Selection Notes
Select this component for designs requiring a simple, low-cost mono amplifier solution. It is suitable for applications where moderate output power is sufficient and efficiency is less critical than simplicity. Consider the thermal performance in the SOIC-8 package when designing the PCB layout. Verify that the supply voltage range aligns with the system's battery or power rail capabilities.
Part Context
This component belongs to the TPA701 series of audio amplifiers from Texas Instruments. It is categorized under linear amplifiers and specifically designed for audio signal processing. The device is part of the broader portfolio of audio ICs offered by the manufacturer, focusing on straightforward integration for basic audio reproduction tasks.
Replacement Considerations
TPA701DRG4 is a verified alternate marking for the same functional device. Check datasheet revisions to ensure pinout and electrical characteristics remain identical before substituting.
