Dual Precision JFET-Input Operational Amplifier OP215
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 VOS, while a 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.
