RFQ ListingAnalog ICs & Data Converters
The INA821IDR is a precision instrumentation amplifier that conditions low-level differential signals with a gain set from 1 to 1000 by a single external resistor. Its 35 µV offset, 8 nV/√Hz noise and 90 dB common-mode rejection make it well suited to bridge, thermocouple and sensor front-ends, while the 4.5 V to 36 V supply and 8-pin SOIC package fit industrial and medical measurement equipment.

Analog Features & Applications
- Single-channel 3-op-amp architecture delivers precise gain from 1 to 1000
- Low 35 µV input offset and 8 nV/√Hz noise preserve small signal accuracy
- Wide 4.5 V to 36 V supply spans industrial and instrumentation rails
- 90 dB CMRR rejects common-mode interference in noisy environments
- 2 V/µs slew rate supports moderately fast signal conditioning
- External gain resistor sets gain without onboard firmware
- Rail-to-rail output maximizes dynamic range on single supplies
- 8-pin SOIC package rated for -40°C to +125°C operation
