17 / 20 page ![]() AD628 Rev. C | Page 17 of 20 CURRENT LOOP RECEIVER Analog data transmitted on a 4 to 20 mA current loop may be detected with the receiver shown in Figure 33. The AD628 is an ideal choice for such a function, because the current loop must be driven with a compliance voltage sufficient to stabilize the loop, and the resultant common-mode voltage often exceeds commonly 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 may be used to monitor a battery charger. Voltages approximately eight times the power supply voltage may 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. +IN –IN G = +0.1 10k Ω 10k Ω AD628 +IN –IN A2 +VS OUT –IN 250 Ω 250 Ω 100k Ω A1 +15V +IN 100k Ω CFILT –VS –15V VREF 10k Ω REXT2 11k Ω REXT1 100k Ω 2.5V REF 0V TO 5V TO ADC 4–20mA SOURCE RG Figure 33.
