9 / 17 page 1-224 Figure 1. Input Offset Voltage Test Circuit. Figure 2. Input-Referred Offset Drift vs. Temperature. 25. Short circuit current is the amount of output current generated when either output is shorted to VDD2 or ground. 26. IMR (also known as CMR or Common Mode Rejection) specifies the mini- mum rate of rise of an isolation mode noise signal at which small output perturbations begin to appear. These output perturbations can occur with both the rising and falling edges of the isolation-mode wave form and may be of either polarity. When the perturba- tions first appear, they occur only occasionally and with relatively small peak amplitudes (typically 20-30 mV at the output of the recommended application circuit). As the magnitude of the isolation mode transients increase, the regularity and amplitude of the perturbations also increase. See applications section for more information. 27. IMRR is defined as the ratio of differential signal gain (signal applied differentially between pins 2 and 3) to the isolation mode gain (input pins tied to pin 4 and the signal applied between the input and the output of the isolation amplifier) at 60 Hz, expressed in dB. 28. Output noise comes from two primary sources: chopper noise and sigma- delta quantization noise. Chopper noise results from chopper stabiliza- tion of the output op-amps. It occurs at a specific frequency (typically 200 kHz at room temperature), and is not attenuated by the internal output filter. A filter circuit can be easily added to the external post-amplifier to reduce the total rms output noise. The internal output filter does eliminate most, but not all, of the sigma-delta quantization noise. The magnitude of the output quantization noise is very small at lower frequencies (below 10 kHz) and increases with increasing frequency. See applications section for more information. 29. Data sheet value is the differential amplitude of the transient at the output of the HCPL-7800 when a 1Vpk-pk, 1 MHz square wave with 5 ns rise and fall times is applied to both VDD1 and VDD2. 30. This is a two-terminal measurement: pins 1-4 are shorted together and pins 5-8 are shorted together. 31. In accordance with UL1577, for devices with minimum VISO specified at 3750 Vrms, each optocoupler is proof- tested by applying an insulation test voltage greater-than-or-equal-to 4500 Vrms for one second (leak current detection limit, II-O <5 µA). This test is performed before the method b, 100% production test for partial discharge shown in the VDE 0884 Insulation Characteristics Table. 32. Case temperature was measured with a thermocouple located in the center of the underside of the package. 1 2 3 4 8 7 6 5 HCPL-7800 +5 V +5 V +15 V 0.1 µF 0.1 µF 0.1 µF 0.1 µF 0.33 µF 0.33 µF 10 K 10 K -15 V AD624CD GAIN = 1000 + - VOUT 1000 500 0 -500 -40 -20 0 20 40 60 80 100 1500 -1000 T – TEMPERATURE – °C A MEAN ± 2 SIGMA |
