Other Parts Discussed in Thread: TINA-TI
Tool/software: TINA-TI or Spice Models
I tried to use the OPA838 with LTspice :-P, however the TINA SPICE model has occrred a floating error at GRA and GRC node.
I have solved this error to modify as below,
* Modified for LTspice by Akihiro Kawata with Fukuda Denshi, Feb/4.2019
* Need to add RA for preventing floating error.
*GRA 101 102 VALUE = {V(101,102)/1e6}
GRA 101 102 101 102 1e-6
RA 102 GNDF 1e12
CA 102 GNDF 1e3
* Modified for LTspice by Akihiro Kawata with Fukuda Denshi, Feb/4.2019
* Need to add RC for preventing floating error.
*GRC 301 302 VALUE = {V(301,302)/1e6}
GRC 301 302 301 302 1e-6
RC 302 GNDF 1e12
CC 302 GNDF 1e3
Node 102 and 303 are connected to CA or CC, it is ideal capacitor, therefore I think some SPICE simulator has occrred the floating node error.
I hope this issue to be corrected by TI.
