Overview of INA821IDR
The INA821IDR is engineered to provide a high common-mode rejection ratio, exceeding 92 dB at a gain of 1 across the full input common-mode range. This makes it well-suited for applications where maintaining signal integrity in the presence of common-mode noise is critical. Furthermore, the device is designed for low-voltage operation, supporting a 4.5-V single supply, as well as dual supplies up to ±18 V
Key Features
- Low offset voltage: 10 µV (typ), 35 µV (max)
- Gain drift: 5 ppm/°C (G = 1),
35 ppm/°C (G > 1) (max) - Noise: 7 nV/√Hz
- Bandwidth: 4.7 MHz (G = 1), 290 kHz (G = 100)
- Stable with 1-nF capacitive loads
- Inputs protected up to ±40 V
- Common-mode rejection: 112 dB, G = 10 (min)
- Power supply rejection: 110 dB, G = 1 (min)
- Supply current: 650 µA (max)
- Supply range:
- Single-supply: 4.5 V to 36 V
- Dual-supply: ±2.25 V to ±18 V
- Specified temperature range: –40°C to +125°C
- Packages: 8-pin SOIC, VSSOP, and WSON
