AD7868ANZ

The AD7868ANZ is a current sense amp and is used to measure current in an in-circuit application. It can measure up to 20V of voltage for both N and P-type MOSFET devices. The AD7868ANZ features an ultra-low offset of 20uV and a wide common-mode input voltage range from -2.5V to 46V. The AD7868ANZ is operational from single supplies of 2.7V to 44V for N-type and 1.5V to 46V for P-type MOSFET devices.

The AD7868ANZ can accurately measure up to 2 amps of DC or AC current with maximum settling times of 20ms. It can be used in virtually any type of conditioning circuit, including voltage dividers, current dividers and instrumentation amplifiers, as well as in high power applications such as motor drive, server power supply and LED lighting. Its small yet efficient package allows it to be integrated into a variety of circuit designs.

The AD7868ANZ operates in the current sense configuration, to detect the value of current in an in-circuit application and convert it into a voltage that can be measured and then amplified. The output voltage provides an envelope of the current flowing through the load connected to it. To form a current sense circuit, the AD7868ANZ needs to be connected to a shunt resistor, which is in series with the load.

The AD7868ANZ is well suited for DC/AC current sensing applications from simple current sensing to complex high-power switchgear and motor drives. It features a low offset of 20uV and an excellent bandwidth of 0.4Hz-10kHz, providing stable peak-to-peak accuracy with less than 1% error in the measurement of peak currents. It is designed to reduce errors due to temperature changes or power supply fluctuations. Its fast settling time of 20ms makes it suitable for applications that require fast response times.

The AD7868ANZ is a great product for applications that require precise current measurement and control, such as motor drives, AC/DC power supplies and UPS systems. Designers can use the AD7868ANZ to build a high-precision current sense circuit that’s ideal for portable and high power applications.
