HJ278 is an amplifier that utilizes unique modulation and demodulation technology, employing transformer isolation, with complete separation of signal and power. HJ278 features three independent grounding terminals, isolating not only the input and output circuits but also the power supply from the amplifier, providing two sets of positive and negative power supplies for the input and output circuits. These power supplies also have terminals for external circuit use. The independent input and output stage amplifiers offer great flexibility for closed-loop applications, allowing various combinations such as in-phase amplification, out-of-phase amplification, current or voltage input and output to meet different isolation amplification needs. This module is compact, has good linearity, an isolation voltage of up to 2500V, powered by a single +5V supply without needing an external DC/DC converter, features input/output zero adjustment terminals, and its three-port structural design allows it to function as an input or output isolator in single or multiple applications while maintaining high performance under continuous common-mode stress.
Its main features are:
Power supply voltage +6V
Input voltage range ±2.5V
Output voltage range ±2.5V
Operating temperature range -20℃~+125℃
Pin soldering temperature(10 seconds) 300℃
