3 / 12 page ADuM7234 Rev. A | Page 3 of 12 SPECIFICATIONS ELECTRICAL CHARACTERISTICS All voltages are relative to their respective ground. 4.5 V ≤ VDD1 ≤ 5.5 V, 12 V ≤ VDDA ≤ 18 V, 12 V ≤ VDDB ≤ 18 V. All minimum/maximum specifications apply over the entire recommended operating range, unless otherwise noted. All typical specifications are at TA = 25°C, VDD1 = 5 V, VDDA = 15 V, VDDB = 15 V.

Average power must conform to the limit shown under the . Absolute Maximum Ratings 2 The minimum pulse width is the shortest pulse width at which the specified timing parameters are guaranteed. 3 The maximum switching frequency is the maximum signal frequency at which the specified timing parameters are guaranteed. 4 tPHL propagation delay is measured from the 50% level of the falling edge of the VIx signal to the 50% level of the falling edge of the VOx signal. tPLH propagation delay is measured from the 50% level of the rising edge of the VIx signal to the 50% level of the rising edge of the VOx signal. 5 Channel-to-channel matching, rising, or falling edges, is the magnitude of the propagation delay difference between two channels of the same part when the inputs are either both rising or falling edges. The supply voltages and the loads on each channel are equal. 6 Channel-to-channel matching, rising vs. falling edges is the magnitude of the propagation delay difference between two channels of the same part when one input is a rising edge and the other input is a falling edge. The supply voltages and loads on each channel are equal. 7 Part-to-part matching, rising or falling edges, is the magnitude of the propagation delay difference between the same channels of two different parts when the inputs are either both rising or falling edges. The supply voltages, temperatures, and loads of each part are equal. 8 Part-to-part matching, rising vs. falling edges, is the magnitude of the propagation delay difference between the same channels of two different parts when one input is a rising edge and the other input is a falling edge. The supply voltages, temperatures, and loads of each part are equal. |
