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 wide bandwidth. Unlike many JFET amplifiers, the AD8610/AD8620input bias current is low over the enTIre operaTIng temperaturerange. The AD8610/AD8620 are stable with capaciTIve loads of over 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 noninverting gain 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.
