NJU8759AGM1T-TE1

Overview

The NJU8759AGM1T-TE1 is a monaural, filterless Class-D power amplifier manufactured by Nisshinbo Micro Devices Inc. It operates on a single supply voltage ranging from 1.8V to 5.5V and delivers up to 3.0W of output power into a 4Ω load at 10% THD+N. The device features an analog differential input with a typical voltage gain of 18dB and utilizes a BTL output configuration that eliminates the need for external LC filters. Key electrical characteristics include a maximum standby current of 1μA, a switching frequency between 100kHz and 395kHz, and a thermal shutdown circuit. It is housed in an HSOP8 package with an exposed pad for heat dissipation.

Feature Summary

• Filterless architecture reduces external component count and PCB size
• Built-in pop noise reduction during turn-on and turn-off sequences
• Integrated protection circuits including overcurrent, thermal shutdown, and undervoltage lockout
• Low standby current consumption suitable for battery-powered applications

Applications

• Security equipment
• Portable audio devices
• Portable electronic equipment

Procurement Notes

Verify the specific ordering suffix TE1 corresponds to the tape and reel packaging format as defined in the manufacturer's documentation. Confirm that the HSOP8 package variant matches the required thermal dissipation specifications for the target application environment. Ensure compatibility with the recommended soldering profiles and mounting methods specified for packages with exposed pads.

Selection Notes

Select this component for designs requiring high efficiency and minimal external filtering in space-constrained portable systems. Consider the thermal resistance characteristics when designing the PCB layout, particularly regarding the exposed pad connection. Evaluate the input signal range and standby control requirements to ensure proper integration with the host system's logic levels and audio sources.
