DescriptionThe AD8221BR belongs to AD8221 family which is a gain programmable, high performance instrumentation amplifier that delivers the industry's highest CMRR over frequency. The CMRR of instrumentation amplifiers on the market today falls off at 200 Hz. In contrast, the AD8221 maintains a minimum CMRR of 80 dB to 10 kHz for all grades at G = 1. High CMRR over frequency allows the AD8221 to reject wideband interference and line harmonics, greatly simplifying filter requirements. The AD8221 is available in low cost 8-lead SOIC and MSOP packages, 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. Performance is specified over the entire industrial temperature range of 40°C to +85°C for all grades. Furthermore, the AD8221 is operational from 40°C to +125°C 1. Possible applications include precision data acquisition, biomedical analysis, and aerospace instrumentation. Low voltage offset, low offset drift, low gain drift, high gain accuracy, and high CMRR make this part an excellent choice in applications that demand the best dc performance possible, such as bridge signal conditioning. Programmable gain affords the user design flexibility. A single resistor sets the gain from 1 to 1000. The AD8221 operates on both single and dual supplies, and is well suited for applications where ±10 V input voltages are encountered.
The features of AD8221BR can be summarized as (1)available in space-saving MSOP package; (2)gain set with 1 external resistor (gain range 1 to 1000); (3)wide power supply range: ±2.3 V to ±18 V; (4)temperature range for specified performance: 40°C to +85°C; (5)operational up to 125°C; (6)excellent ac specificatons: 80 dB min CMRR to 10 kHz ( G = 1), 825 kHz 3 dB bandwidth (G = 1), 2 V/s slew rate; (7)low noise: 8 nV/Hz, @ 1 kHz, max input voltage noise, 0.25 V p-p input noise (0.1 Hz to 10 Hz); (8)high accuracy dc performance (AD8221BR), 90 dB min CMRR (G = 1), 25 V max input offset voltage, 0.3 V/°C max input offset drift, 0.4 nA max input bias current.
The absolute maximum ratings of AD8221BR are (1)supply voltage: ±18 V; (2)internal power dissipation: 200 mW; (3)output short circuit current: indefinite; (4)input voltage (common-mode): ±V S; (5)differential input voltage: ±Vs; (6)storage temperature: 65°C to +150°C; (7)operational*(*Temperature range for specified performance is 40°C to +85°C.
