Designed for conditioning low-level differential signals (such as from current shunt resistors or bridge sensors) in the presence of high common-mode voltage, it provides 86dB minimum CMRR at G=100 and \u00b150V input overvoltage protection. The built-in single-pole low-pass filter reduces high-frequency noise. Operates from single 2.4V to 36V or dual \u00b11.2V to \u00b118V supplies in a 14-pin PDIP package.","working_principle":"The AD626 uses a precision differential input stage followed by a gain stage and output buffer. At G=10, a feedback network sets the gain while maintaining wide bandwidth (100kHz). At G=100, an additional gain stage is inserted with reduced bandwidth (10kHz) but higher CMRR (86dB). The integrated low-pass filter can be configured with an external capacitor for custom cutoff frequency. The input stage includes overvoltage protection clamps to \u00b150V, protecting the amplifier from transient voltages in harsh automotive or industrial environments.","pin_description":"
