GENERAL DESCRIPTION

The ADI-JFET input series of devices offer clear advantages over

industry-generic devices and are superior in both cost and perfor-

mance to many dielectrically-isolated and hybrid op amps. All devices

offer offset voltages as low as 0.5 mV with TCV

5 mV/HC. A unique input bias cancellation circuit reduces the I

by a factor 10 over conventional designs. In addition ADI specifies

These devices were designed to provide real precision performance

along with high speed. Although they can be nulled, the design

objective was to provide low offset-voltage without nulling. Systems

generally become more cost effective as the number of trim circuits

is decreased. ADI achieves this performance by use of an improved

bipolar compatible JFET process coupled with on chip, zener-zap

offset trimming.

The OP15 provides an excellent combinations of high speed and

low input offset voltage. In addition, the OP15 offers the speed

of the 156A op amp with the power dissipation of a 155A. The

combination of a low input offset voltage of 500 mV, slew rate of

13 V/ms, and settling time of 1,200 ns to 0.1% makes the OP15

an op amp of both precision and speed. The additional features

of low supply current coupled with an input bias current makes

the OP15 ideal for a wide range of applications.

The OP17 has a slew rate of 60 V/ms and is the best choice for

applications requiring high closed-loop gain with high speed. See

OP42 datasheet for unity gain applications and the OP215 datasheet

for a dual configuration of the OP15.
