INA821IDR TI Instrumentation, OP Amps, Buffer Amps
The INA821 is a precision instrumentation amplifier with a wide supply range of 4.5-V to 36-V single supply (or ±2.25-V to ±18-V dual), featuring rail-to-rail output. Gain is set by a single external resistor from 1 to 10,000. It achieves low 10-nV/√Hz noise, 100-dB minimum CMRR at G = 10, and low offset voltage of 35 µV. Packaged in an 8-pin SOIC (D) (4.9 mm × 3.91 mm), it is ideal for industrial and medical applications requiring high precision. Applications include medical ECG/EEG monitoring, industrial strain gauges, pressure sensors, and differential current sensing. In stock at HL Electronics – request a quote for fast delivery.
