AD8610ARMZ-R7

The AD8610/AD8620 are very high precision JFET input amplifiers featuring ultralow offset voltage and drift, very low input
voltage and current noise, very low input bias current, and wide
bandwidth. Unlike many JFET amplifiers, the AD8610/AD8620
input bias current is low over the entire operating temperature
range. The AD8610/AD8620 are stable with capacitive loads of
over 1000 pF in noninverting unity gain; much larger capacitive
loads can be driven easily at higher noise gains. The AD8610/
AD8620 swing to within 1.2 V of the supplies even with a 1 kΩ
load, maximizing dynamic range even with limited supply voltages. Outputs slew at 50 V/μs in either inverting or noninverting
gain configurations, and settle to 0.01% accuracy in less than
600 ns. Combined with high input impedance, great precision,
and very high output drive, the AD8610/AD8620 are ideal
amplifiers for driving high performance ADC inputs and
buffering DAC converter outputs.
Applications for the AD8610/AD8620 include electronic instruments; ATE amplification, buffering, and integrator circuits;
CAT/MRI/ultrasound medical instrumentation; instrumentation
quality photodiode amplification; fast precision filters (including
PLL filters); and high quality audio.
The AD8610/AD8620 are fully specified over the extended
industrial temperature range (−40°C to +125°C). The AD8610
is available in the narrow 8-lead SOIC and the tiny 8-lead MSOP
surface-mount packages. The AD8620 is available in the narrow
8-lead SOIC package. The 8-lead MSOP packaged devices are
avail-able only in tape and reel.
