General Description
The ET852SXXX series consists of single and dual-channel amplifiers with extremely high precision, featuring ultra-low offset voltage, temperature drift, low input bias current, low noise, and low power consumption. It maintains output stability under capacitive loads of 50pF without external compensation. The amplifier includes a built-in 100Ω series input protection resistor, ensuring no phase inversion even when input signal levels exceed the power supply voltage by several volts. The ET852SXXX series amplifiers are available in both SOP8 and MSOP8 packages. With a rated operating temperature range of -40°C to +125°C, this product meets the demands of harsh working environments.
The application of this product includes precision diode power measurement, voltage and current level setting, and level detection in optical and wireless transmission systems. Other applications include but are not limited to the following types of circuit power supply and portable instruments and control circuits: thermocouples, resistance temperature detectors, strain bridges, as well as sensor signal conditioning, precision filters, etc.
