Digital Isolators are essential instruments that ensure signal integrity between two isolated sections of a circuit. The LTC4310CDD-2#PBF is a digital isolator designed to provide a bridge between a high-speed digital signal and a low-speed signal, such as a 4, 12, or 16bit data word.

This isolation device is able to separate the power and signal paths within a circuit, while providing excellent noise immunity and a wide working temperature range. The device provides an I/O isolation barrier of up to 5kVrms/min, allowing it to operate reliably in harsh environments.

The LTC4310CDD-2#PBF comes in a tiny 4-pin package measuring only 2.2 x 1.2x 0.4” (5.7 x 3 x 1 mm). This makes it easy to incorporate the digital isolator into space-constrained designs. Additionally, the device features a low power consumption of 1.9 mA supply current (typical).

The LTC4310CDD-2#PBF is designed for high-accuracy data acquisition and control applications, such as industrial motor control, air and flow sensing, and medical device control. It can also be used in power-sensitive applications, such as electrical power meters, and in many other applications requiring digital signal isolation.

The digital isolator’s working principle is based on galvanic isolation, using an optocoupler-based isolation barrier to provide data transmission between two digitally isolated sections of a circuit. The device uses low impedance transmission lines to minimize the voltage and current noise of a signal, and pass the signal directly to the output with no propagation delay.

The device also features a high common-mode transient immunity of up to 50 kV/μs (min). This significantly prevents common mode noise from affecting the data transfer, ensuring that the signal is reliably transmitted without errors. The LTC4310CDD-2#PBF also supports an output slew rate of up to 3.2 V/μs, allowing it to handle high-speed data acquisition or control signals.

In summary, the LTC4310CDD-2#PBF digital isolator ensures reliable signal transmission between two isolated sections of a circuit, allowing it to be widely used in design applications requiring high isolation accuracy and dependability. It provides an I/O isolation barrier of up to 5kVrms/min, allowing it to operate reliably in harsh environments. The device features a low power consumption of 1.9 mA supply current (typical), and a high common-mode transient immunity of up to 50 kV/μs (min). Moreover, the device also supports an output slew rate of up to 3.2 V/μs, allowing it to handle high-speed data acquisition or control signals.
