AD8221 datasheet

Description :

The AD8221 is a gain programmable, high performance instrumentation amplifier that delivers the industry’s highest CMRR over frequency in its class. The CMRR of instrumentation amplifiers on the market today falls off at 200 Hz. In contrast, the device maintains a minimum CMRR of 80 dB to 10 kHz for all grades at G = 1. High CMRR over frequency allows the IC to reject wideband interference and line harmonics, greatly simplifying filter requirements. Possible applications include precision data acquisition, biomedical analysis, and aerospace instrumentation.

Features

1. Easy to use
2. Available in space-saving MSOP
3. Gain set with 1 external resistor (gain range 1 to 1000)
4. Wide power supply range : ±2.3 V to ±18 V
5. Temperature range for specified performance :  −40°C to +85°C
6. Excellent AC specifications
7. 80 dB minimum CMRR to 10 kHz (G = 1)
8. 8 nV/√Hz, @ 1 kHz, maximum input voltage noise
9. 0.25 µV p-p input noise (0.1 Hz to 10 Hz)
10. High accuracy dc performance (AD8221BR)

Applications : 

1. Weigh scales
2. Industrial process controls
3. Bridge amplifiers
4. Precision data acquisition systems
5. Medical instrumentation
6. Strain gages
7. Transducer interfaces
