Hi Team,
A customer has this board but they are having 10x attenuated output and not unity gain.
The board was assembled as per the schematic with the corresponding value:
Rin1 = 50 ohms; Rin2 = 25 ohms; Rout 1= 50 ohms; Rout2= 25 ohms; Cbpu and Cbnu = 4.7uF; Cpn= 10nF; Cbpn, Cbpp= 0.1uF.
Rmid and Cmid were not connected; The Lp and Ln were replaced by 0ohm.
The board is supplied by dual voltage +/-5V
When the customer applies sine wave signal 1v peak to peak, the output they are getting is 100mV peak to peak.
Can you help?
Thanks in advance.
Regards,
Marvin
