Preliminary Technical Data

ADM2682E/ADM2687E

Rev. PrE | Page 3 of 20

SPECIFICATIONS

All voltages are relative to their respective ground; 3.0 ≤ VCC ≤ 5.5 V. All minimum/maximum specifications apply over the entire

recommended operation range, unless otherwise noted. All typical specifications are at TA = 25°C, VCC = 5 V unless otherwise noted.

VCM = 1 kV, transient magnitude = 800 V

1

CM is the maximum common-mode voltage slew rate that can be sustained while maintaining specification-compliant operation. VCM is the common-mode potential

difference between the logic and bus sides. The transient magnitude is the range over which the common-mode is slewed. The common-mode voltage slew rates

apply to both rising and falling common-mode voltage edges.
