GENERAL DESCRIPTION
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.
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.
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.
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

NOTES
1Input bias current is specified for two different conditions. The Tj = 25∞C specification is with the junction at ambient temperature; the device operating specification is
with the device operating in a warmed up condition at 25∞C ambient. The warmed up bias-current value is correlated to the junction temperature value via the curves
of IS versus Tj and IS versus TA. PMI has a bias-current compensation circuit that gives improved bias current and bias current over temperature versus standard
JFET input op amps. IS and IOS are measured at VCM = 0.
2Setting time is defined here for a unity gain inverter connection using 2 kW resistors. It is the time required for the error voltage (the voltage at the inverting input pin
on the amplifier) to settle to within a specified percent of its final value from the time a 10 V step input is applied to the inverter. See setting time test circuit.

2Not for new design, obsolete April 2002.
CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection. Although
the OP215 features proprietary ESD protection circuitry, permanent damage may occur on devices
subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are
recommended to avoid performance degradation or loss of functionality.

As with most amplifiers, care should be taken with lead dress,
component placement, and supply de-coupling in order to ensure
stability. For example, resistors from the output to an input should
be placed with the body close to the input to minimize “pick up”
and maximize the frequency of the feedback pole by minimizing
the capacitance from the input to ground.

A feedback pole is created when the feedback around any amplifier
is resistive. The parallel resistance and capacitance from the
input of the device (usually the inverting input) to ac ground
sets the frequency of the pole. In many instances, the frequency
of this pole is much greater than the expected 3 dB frequency of
the closed-loop gain and, consequently, there is negligible effect
on stability margin. However, if the feedback pole is less than
approximately six times the expected 3 dB frequency, a lead
capacitor should be placed from the output to the negative input
of the op amp. The value of the added capacitor should be such
that the RC time constant of this capacitor and the resistance it
parallels is greater than, or equal to, the original feedback pole
time constant.
