AD8620AR-REEL7 GENERAL DESCRIPTION

The AD8610/AD8620 are very high precision JFET input ampli-fiers featuring ultralow offset voltage and drift, very low inputvoltage and current noise, very low input bias current, and widebandwidth. Unlike many JFET amplifiers, the AD8610/AD8620input bias current is low over the entire operating temperaturerange. The AD8610/AD8620 are stable with capacitive loads ofover 1000 pF in noninverting unity gain; much larger capacitiveloads can be driven easily at higher noise gains. The AD8610/AD8620 swing to within 1.2 V of the supplies even with a 1 kΩload, maximizing dynamic range even with limited supply volt-ages. Outputs slew at 50 V/μs in either inverting or noninvertinggain configurations, and settle to 0.01% accuracy in less than600 ns. Combined with high input impedance, great precision,and very high output drive, the AD8610/AD8620 are idealamplifiers for driving high performance ADC inputs andbuffering DAC converter outputs.Applications for the AD8610/AD8620 include electronic instru-ments; ATE amplification, buffering, and integrator circuits;CAT/MRI/ultrasound medical instrumentation; instrumentationquality photodiode amplification; fast precision filters (includingPLL filters); and high quality audio.The AD8610/AD8620 are fully specified over the extendedindustrial temperature range (−40°C to +125°C). The AD8610is available in the narrow 8-lead SOIC and the tiny 8-lead MSOPsurface-mount packages. The AD8620 is available in the narrow8-lead SOIC package. The 8-lead MSOP packaged devices areavail-able only in tape and reel.
