AD8293G160BRJZ-RL GENERAL DESCRIPTION

The AD8293G80/AD8293G160 are small, low cost, precisioninstrumentation amplifiers that have low noise and rail-to-railoutputs. They are available in two fixed-gain models: 80 and 160.They incorporate the gain setting resistors and filter resistors,reducing the number of ancillary components. For example,only two external capacitors are needed to implement a 2-polefilter. The AD8293G80/AD8293G160 also feature low offsetvoltage, offset drift, and gain drift coupled with high common-mode rejection. They are capable of operating on a supply of1.8 V to 5.5 V.With a low offset voltage of 20 μV (AD8293G160B), an offsetvoltage drift of 0.3 μV/°C, and a voltage noise of only 0.7 μV p-p(0.01 Hz to 10 Hz), the AD8293G80/AD8293G160 are idealfor applications where error sources cannot be tolerated.Precision instrumentation, position and pressure sensors,medical instrumentation, and strain gauge amplifiers benefitfrom the low noise, low input bias current, and high common-mode rejection. The small footprint and low cost are ideal forhigh volume applications.The small package and low power consumption allow the maxi-mum channel density and the minimum board size required forportable systems. Designed for ease of use, these instrumentationamplifiers, unlike more traditional ones, have a buffered reference,eliminating the need for an additional op amp to set the referencevoltage to midsupply.The AD8293G80/AD8293G160 are specified over the industrialtemperature range from −40°C to +85°C. The AD8293G80/AD8293G160 are available in a halogen-free, Pb-free, 8-lead SOT-23.
