AD8418AWHRZ

The AD8418AWHRZ is a dual-channel, high impedance, low-noise amplifier used in instrumentation applications. It is part of the Linear - Amplifiers - Instrumentation, OP Amps, Buffer Amps product family, and is suitable for a wide range of applications including audio, mechanical, and electrical measurement, as well as high-fidelity recording. The device features high-impedance differential inputs, low-noise current source output, and a low quarternary offset voltage, which makes it ideal for precision measurements and audio quality.

The AD8418AWHRZ is a low-power device with a maximum supply voltage of 7V and a maximum supply current of just 3.4mA. The device operates over a -40 °C to +85 °C temperature range. Its dual channels offer a wide input-offset voltage range of ±300mV and a low input-bias current of 1.5nA. With a wide common-mode voltage range from -6V to +6V, the AD8418AWHRZ is suitable for high and low side LVDS measurements.

The AD8418AWHRZ features a wide band, low-noise amplifier with a -3 dB bandwidth of 500 kHz, making it suitable for a wide range of instrumentation and low-speed data acquisition applications. It has a low input-offset voltage of just 3mV and a low-crosstalk of less than 0.5°. The device also offers excellent common-mode rejection ratio (CMRR) of 78 dB, making it ideal for applications that require high precision signals. It also offers a high slew rate of 28 V/μs for accurate signals.

The typical operating control voltage range of the device is from 200 mV to +6 V, making it suitable for data acquisition systems that operate from a supply voltage as low as 200 mV. It has two separate dc gain settings that include a lower-gain setting of 25 dB with an -3 dB corner frequency of 100 kHz and a higher-gain setting of 29 dB with an -3 dB corner frequency of 5MHz. This allows for higher levels of accuracy and precision in measurements. The device also features a low power-supply rejection ratio (PSRR) of 76 dB, ensuring a high accuracy in measurements.

The AD8418AWHRZ is a versatile device that is suitable for a wide range of instrumentation and data acquisition applications.
