GENERAL DESCRIPTION
The AD8610/AD8620 is a very high precision JFET input amplifier
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 is 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 swings to
within 1.2 V of the supplies even with a 1 k
load, maximizing
dynamic range even with limited supply voltages. Outputs slew at
50 V/
μ
s in either inverting or noninverting gain configurations, and
settle to 0.01% accuracy in less than 600 ns. Combined with the
high input impedance, great precision, and very high output drive, the
AD8610/AD8620 is an ideal amplifier for driving high performance
A/D inputs and buffering D/A converter outputs.
Applications for the AD8610/AD8620 include electronic instru-
ments; 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 is fully specified over the extended
industrial (–40
°
C to +125
°
C) temperature range. The AD8610
is available in the narrow 8-lead SOIC and the tiny MSOP8
surface-mount packages. The AD8620 is available in the narrow
8-lead SOIC package. MSOP8 packaged devices are available
only in tape and reel.
