CURRENT LOOP RECEIVER
Analog data transmitted on a 4 to 20 mA current loop can be
detected with the receiver shown in Figure 33. The AD628 is an
ideal choice for such a function because the current loop is
driven with a compliance voltage sufficient to stabilize the loop,
and the resultant common-mode voltage often exceeds com-
monly used supply voltages. Note that with large shunt values, a
resistance of equal value must be inserted in series with the
inverting input to compensate for an error at the noninverting
input.
MONITORING BATTERY VOLTAGES
Figure 34 illustrates how the AD628 is used to monitor a battery
charger. Voltages approximately eight times the power supply
voltage can be applied to the input with no damage. The resistor
divider action is well-suited for the measurement of many
power supply applications, such as those found in battery
chargers or similar equipment.
