 		 #68022 - RE: ULN2803 Output droping at 3KHz.
Responding to: ???'s previous message
Hello Prahlad,
Take some measurements at 500, 1000, 1500, 2000, 2500 and 3000 kHz. This should tell you where the problem starts to develop. Plot out the results and if the curve starts to drop before 3000 kHz then that is an indication you are getting involved into inductance problems.
Regards,
Charles Bannister
