The ADUM4190SRIZ is a precision CMOS analog isolator that can be used in a variety of analog signal applications, including linear amplifiers, special purpose applications, and much more. This isolator is designed to transfer analog signals between two isolated power domains while maintaining high levels of precision and excellent noise immunity. It has a wide operating temperature range (-40 to 85°C) and a fast response time (under 10µs).

The ADUM4190SRIZ is a single-channel device with a built-in 3kV rms isolation barrier, operating from 0 to 36V supply voltage. It has a wide dynamic range of gain (-2.5 to 32dB -1.7 to 30dB at 0.5 percent linearity), high linearity over the entire gain range (0.1 percent typical), and low power consumption (11mW @ 5V). The device has a low-frequency cut-off of 1kHz, making it suitable for use in linear and special purpose applications where lower frequency signals need to be handled.

In linear amplifier applications, the ADUM4190SRIZ can be used for signal isolation, impedance matching, gain adjustment, and noise cancellation. As it is a CMOS device, it can be used in both single-ended and differential signal paths. Its wide linearity, wide gain range, and low-frequency cut-off make it suitable for use in a variety of analog signal applications. The device has a wide dynamic range of gain (-2.5 to 33dB -1.7 to 30dB at 0.5 percent linearity) making it ideal for use in applications requiring low distortion.

In applications using differential signals, the ADUM4190SRIZ can be used for signal isolation and bridge-to-differential output conversion. The device offers high precision and excellent noise immunity and can be used in applications that require accurate signal transmission in noisy environments. It can also be used in special purpose applications such as programmable gain amplifiers, voltage-controlled amplifiers, and current-controlled amplifiers.

To enable ease of use, the ADUM4190SRIZ comes with an integrated EEPROM, which can be programmed to adjust the gain range and linearity. The EEPROM also allows for the addition of additional features, such as hysteresis, adaptive gain control, start-up configuration, protected operation, and more.
