NJU8713V-TE1

Overview

The NJU8713V-TE1 is a switching driver for Class D amplifiers manufactured by Nisshinbo Micro Devices Inc. It features separated power source terminals between input and output, along with BEEP and BPZ (Bipolar Zero) output circuits. The device converts 1-bit digital signals, such as PWM or PDM, into analog outputs via an external LC low-pass filter. Operating on CMOS technology, it supports an operating voltage range of 1.7V to 2.7V and a driving voltage from 1.7V to VDD. It includes internal BPZ charging capabilities and is housed in an SSOP14 package.

Feature Summary

• Supports 2-channel 1-bit audio signal inputs
• Includes standby (Hi-Z), BPZ control, and beep functions
• Features an internal BPZ charger
• Utilizes CMOS technology for high power efficiency

Applications

• Portable audio sets
• Stereo OTL headphone amplifier circuits
• 1-channel BTL speaker amplifier configurations

Procurement Notes

Verify the specific ordering suffix 'V-TE1' against official manufacturer documentation to confirm exact reel specifications and tape-and-reel dimensions. Ensure compatibility with the required SSOP14 footprint during PCB layout. Confirm that the logic supply (VDD) and driving supply (VDDO) requirements align with your system's power architecture before finalizing procurement.

Selection Notes

Select this component for applications requiring high-efficiency Class D amplification with integrated control features like Beep and Bipolar Zero. It is suitable for portable devices where power efficiency is critical. Ensure the design accommodates separate logic and driving power supplies and provides adequate decoupling for the VDDO rail to maintain low Total Harmonic Distortion (THD).

Part Context

This part belongs to the NJU8713 series of switching drivers designed specifically for Class D audio amplification. It integrates essential control logic for managing audio signal routing and output states directly within the driver IC. The series is engineered to simplify the implementation of efficient audio systems by combining the driver stage with necessary auxiliary functions.
