GENERAL DESCRIPTION

The OP215 offers the proven JFET-input performance advantages

of high speed and low input bias current with the tracking and

convenience advantages of a dual op amp configuration.

Low input offset voltages, low input currents, and low drift are

featured in these high-speed amplifiers.

On-chip zener-zap trimming is used to achieve low V

bias-current compensation scheme gives a low input bias current

REV. A

at elevated temperature. Thus, the OP215 features an input bias

current of 1.4 nA at 70∞C ambient (not junction) temperature

which greatly extends the application usefulness of this device.

Applications include high-speed amplifiers for current output

DACs, active filters, sample-and-hold buffers, and photocell

amplifiers. For additional precision JFET op amps, see the

OP249 and AD712 data sheets.
