XTR111: IS and VG pin

Amy Luo

Part Number: XTR111

Hi Team,

When using XTR111, the definitions of pins 2 (IS) and 3 (VG) are not very clear, how they work and what signals they output. What are the output signal waveforms of the two pins? Could you help me clarify it? Thank you in advance

Regards,

Amy

Hi Tamara,

Thank you very much for your reply.

I have another question：

What damage does the SET pin （pin7）of XTR111 cause when it is short to ground or open? Is there a limit protection circuit inside it? How does its actual output change?

Regards,

Amy

Hi Amy,

RSET sets the transconductance for the circuit. Follow the equation on page 1: Iout = 10(VIN/RSET).

If RSET is left open, Iout will go to 0.

Hope that helps.
