The Texas Instruments INA821IDR is a versatile instrumentation amplifier designed for precision measurement applications. It features a high bandwidth of 4.7 MHz at minimum gain and a low noise density of 7 nV/√Hz, making it suitable for amplifying small differential signals.
Key electrical specifications include a low input offset voltage of 35 µV maximum and a low input offset drift of 0.4 µV/°C maximum. The device supports a wide supply voltage range from 4.5 V to 36 V for single supply and ±2.25 V to ±18 V for dual supply. It offers a high common-mode rejection ratio (CMRR) of 136 dB and a power supply rejection ratio (PSRR) of 110 dB.
The INA821IDR is available in multiple package options: 8-pin SOIC, 8-pin VSSOP, and 8-pin WSON. These packages offer different footprints, with the WSON being the smallest at 9 mm².
This instrumentation amplifier is designed for applications requiring high accuracy and low power consumption, such as industrial process control, medical instrumentation, and data acquisition systems.
