TC7652 TC7652 ELECTRICAL SPECIFICATIONS (CONTINUED) Electrical Characteristics:
VDD = +5V, VSS = -5V, TA = +25°C, unless otherwise indicated.
Symbol Parameter Min Typ Max Units Test Conditions
IS Supply Current — 1 3 mA No Load fCH Internal Chopping Frequency 100 275 — Hz Pins 12 – 14 Open (DIP) Clamp ON Current (
Note 3
) 25 100 — A RL = 100k Clamp OFF Current (
Note 3
) — 1 — pA -4V VOUT < +10V
Note 1:
Limiting input current to 100A is recommended to avoid latch-up problems. Typically 1mA is safe however, this is not guaranteed.
2:
Output clamp not connected. See typical characteristics curves for output swing versus clamp current characteristics.
