Constant-Voltage/Constant-Current Power Supply
The constant-voltage/constant-current power supply shown
in Figure 8 uses the CA3240E1 as a voltage-error and cur-
rent-sensing amplifier. The CA3240E1 is ideal for this appli-
cation because its input common-mode voltage range
includes ground, allowing the supply to adjust from 20mV to
25V without requiring a negative supply voltage. Also, the
ground reference capability of the CA3240E1 allows it to
sense the voltage across the 1
current-sensing resistor in
the negative output lead of the power supply. The CA3086
transistor array functions as a reference for both constant-
voltage and constant-current limiting. The 2N6385 power
Darlington is used as the pass element and may be required
to dissipate as much as 40W. Figure 9 shows the transient
response of the supply during a 100mA to 1A load transition.
Precision Differential Amplifier
Figure 10 shows the CA3240E in the classical precision dif-
ferential amplifier circuit. The CA3240E is ideally suited for
biomedical applications because of its extremely high input
impedance. To insure patient safety, an extremely high elec-
trode series resistance is required to limit any current that
might result in patient discomfort in the event of a fault condi-
tion. In this case, 10M
resistors have been used to limit the
current to less than 2
μ
A without affecting the performance of
the circuit. Figure 11 shows a typical electrocardiogram
waveform obtained with this circuit.
NOTE:

At 220V operation, TRIAC should be T2300D, R
S
= 18K, 5W.
