3 / 19 page  Data Sheet ADM3050E Rev. B | Page 3 of 19 SPECIFICATIONS All voltages are relative to their respective ground, 1.7 V ≤ VDD1 ≤ 5.5 V, 4.5 V ≤ VDD2 ≤ 5.5 V, and −40°C ≤ TA ≤ +125°C, unless otherwise noted. Typical specifications are at VDD1 = VDD2 = 5 V and TA = 25°C, unless otherwise noted. Table 1.
