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

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.
