Description

The return of CC would go to ground if there were such a pin; however op amps traditionally have no ground and the capacitor current will return to one or both OPA548 , and OPA549 series power operational amplifiers for high output current drive, along with programmable current limit and output disable capability. 3 Description. The OPA188 operational amplifier uses TIs proprietary auto- zeroing techniques to provide low offset voltage (25- V maximum) and near zero -drift. +25V. 25V. NOTES: (1) 4.7 F tantalum recommended. (2) Current limit set resistor 14.7k = 2.5A. EMF. R2. R3. 5k . RM. RCL. RM = 12 . OPA548 . 10k . R1. INTRODUCTION. Many applications require current sources to excite various devices for sensor drive, accurate measurement, and other applications.
