Description

The AD8221BR 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 AD8221BR maintains a minimum CMRR of 80 dB to 10 kHz for all grades at G = 1. High CMRR over frequency allows the AD8221BR to reject wideband interference and line harmonics, greatly simplifying filter requirements. Possible applications include precision data acquisition, biomedical analysis, and aerospace instrumentation.Programmable gain affords the user design flexibility. A single resistor sets the gain from 1 to 1000. The AD8221BR operates on both single and dual supplies and is well suited for applications where ±10 V input voltages are encountered.The AD8221BR is available in a low cost 8-lead SOIC and 8-lead MSOP, both of which offer the industry’s best performance. The MSOP requires half the board space of the SOIC, making it ideal for multichannel or space-constrained applications. AD8221BR Features • Easy to use• Available in space-saving MSOP• Gain set with 1 external resistor (gain range 1 to 1000)• Low noise- 8 nV/√Hz, @ 1 kHz, maximuminput voltage noise - 0.25 µV p-p input noise (0.1 Hz to 10 Hz) AD8221BR Applications • Weigh scales• Industrial process controls• Bridge amplifiers• Precision data acquisition systems• Medical instrumentation• Strain gages• Transducer interfaces
