PRODUCT DESCRIPTION

The AD647 is an ultralow drift, dual JFET amplifier that com-

bines high performance and convenience in a single package.

The AD647 uses the most advanced ion-implantation and laser

wafer drift trimming technologies to achieve the highest perfor-

mance currently available in a dual JFET. Ion-implantation per-

mits the fabrication of matched JFETs on a monolithic bipolar

chip. Laser wafer drift trimming trims both the initial offset volt-

age and its drift with temperature to provide offsets as low as

100 µV (250 µV max) and drifts of 2.5 µV/°C max.

PRODUCT HIGHLIGHTS

1. The AD647 is guaranteed and tested to tight matching speci-

fications to ensure high performance and to eliminate the se-

lection and matching of single devices.

2. Laser wafer drift trimming reduces offset voltage and offset

In addition to outstanding individual amplifier performance, the

AD647 offers guaranteed and tested matching performance on

critical parameters such as offset voltage, offset voltage drift and

bias currents.

voltage drifts to 250 µV and 2.5 µV/°C max.

3. Voltage noise is guaranteed at 4 µV p-p max (0.1 Hz to

10 Hz) on K, L and S grades.

4. Bias current (35 pA K, L, S; 75 pA J) is specified after five

minutes of operation.

The high level of performance makes the AD647 especially well

suited for high precision instrumentation amplifier applications

that previously would have required the costly selection and

matching of space wasting single amplifiers.

5. Total supply current is a low 2.8 mA max.

6. High open loop gain ensures high linearity in precision instru-

mentation amplifier applications.

The AD647 is offered in four performance grades, three com-

mercial (the J, K and L) and one extended (the S). All are sup-

plied in hermetically sealed 8-pin TO-99 packages and are

available processed to MIL-STD-883B. The LCC version is

also available processed to MIL-STD-883B.

7. The standard dual amplifier pinout permits the direct substi-

tution of the AD647 for lower performance devices.

8. The AD647 is available in chip form.
