Working Principle

The AD7151BRMZ-REEL operates as a two-wire interface for connecting sensor and controller nodes. It supports differential pair communication and provides an ultra-low power, low noise and high-speed communication interface. The ASIC consists of a transmitter (TX) and receiver (RX) circuit, where both modules share the same power and ground lines. The TX circuit converts the digital inputs into differential signals to be transmitted over the two-wire interface. The RX circuit receives the differential signals and converts them back to digital outputs. The transmitter and receiver have dedicated analog power and ground pins, providing isolation and improved system performance. With its integrated ESD protection, it can withstand high-voltage transients, making it suitable for applications in harsh environments. The AD7151BRMZ-REEL can operate on a voltage range of 2V to 6V and has an operating current of 6.7mA and a standby current of only 500nA. It has a maximum operating temperature of 125ºC and a data rate of up to 100MHz. The chip comes in a QFN package, with an 11.5mm x 11.5mm size.
