GENERAL DESCRIPTION

AD8610/AD8620 is an ideal amplifier for driving high performance

A/D inputs and buffering D/A converter outputs.

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 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 the

high input impedance, great precision, and very high output drive, the

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.
