Product Description
onsemi NCS5651MNTXG is a dual operational amplifier featuring an 80 MHz gain bandwidth product, provided in a compact 20-Pin QFN package designed for surface mount assemblies. It supports a supply voltage range of 6V to 12V and is intended for applications requiring high output current and low distortion.
This device employs a high-efficiency Class A/B architecture optimized for power line communication (PLC) modems and robust power amplification needs. It integrates two operational amplifiers: a high current output amplifier capable of sourcing 1.5 A with rail-to-rail voltage operation, and a small-signal amplifier configurable as a unity gain buffer or part of a 4-pole low-pass filter.
Designed for reliable operation in harsh environments, the NCS5651MNTXG features two independent thermal flags with hysteresis to warn and protect against over-temperature conditions. The thermal warning flag can be customized for threshold setting, while the thermal error flag initiates shutdown upon exceeding 150°C internal junction temperature. Current limiting is programmable through a single resistor, enhancing device protection.
With a small footprint of 4 mm length, 4 mm width, and 0.95 mm height, this surface mount device fits compact industrial designs and automotive applications, although it is not rated as an automotive standard device. It supports operation from -40°C to 125°C ensuring performance across a wide temperature range.
The NCS5651MNTXG is ideal for industrial sectors including power line communications, motor driver circuits, actuators, and other applications demanding robust power amplifiers with built-in diagnostics.
Its rail-to-rail output stage and programmable thermal flags simplify integration and improve system reliability. Current limit and thermal error functions reduce risk of device damage from overheating or overcurrent conditions.
The device’s compact QFN package supports automated assembly and space-limited designs. Typical uses include manufacturing, industrial automation, HVAC, and automotive electronics.
