REF02
PRECISION CURRENT SOURCE
A current source with 35 V output compliance and excellent
output impedance can be obtained using this circuit. REF02
keeps the line voltage and power dissipation constant in the
device; the only important error consideration at room
SUPPLY BYPASSING
For best results, it is recommended that the power supply pin be
bypassed with a 0.1 μF disc ceramic capacitor.
I OUT
temperature is the negative supply rejection of the op amp. The

VOLTAGE COMPLIANCE: –9V TO +25V
typical 3 μV/V PSRR of the OP02E creates a 20 ppm change
(3 μV/V × 35 V/5 V) in output current over a 25 V range. For
example, a 5 mA current source can be built (R = 1 k?) with
350 M? output impedance.
