A single external resistor sets any gain from 1 to 1000 with excellent gain drift of only 35 ppm\/\u00b0C max (G>1). The device achieves 104dB min CMRR at G=10 (maintaining 100dB at 5kHz), 150\u03bcV max offset voltage, and rail-to-rail output for maximum dynamic range. Input protection circuitry limits input currents to less than 8mA for voltages up to \u00b140V beyond the supplies, providing robust fault tolerance in industrial environments.","working_principle":"The INA826 uses a current-feedback three-op-amp instrumentation amplifier topology. The input stage employs matched PNP transistors (Q1, Q2) that level-shift the input voltages up by a diode drop, enabling the common-mode range to include the negative supply rail. Internal amplifiers A1 and A2 drive current through the gain-setting resistor RG, and the resulting differential current is mirrored to the output stage A3. The gain equation is G = 1 + (49.4k\u03a9 \/ RG), where a single external resistor RG sets the gain from 1 (RG open) to 1000 (RG \u2248 49.4\u03a9). The rail-to-rail output stage maximizes dynamic range at low supply voltages. Input protection uses series resistors and clamping diodes to limit current to 8mA for input voltages up to \u00b140V beyond the supplies.","pin_description":"
