TROUBLESHOOTING GUIDE
Top Ten LTC1966 Application Mistakes
1. Circuit wont workDead On Arrivalno power drawn.
 Probably forgot to enable the LTC1966 by pulling
  Pin? low.
  Solution: Tie Pin 8 to Pin 1.
2. Circuit wont work, but draws power. Zero or
 
very little output, single-ended input application.
 Probably didnt connect both input pins.
  Solution: Tie both inputs to something. See Input
  Connections in the Design Cookbook.

4. Gain is low by a few percent, along with other screwy
results.
   Probably tried to use output in a floating, differential
  manner.
  Solution: Tie Pin 6 to a low impedance. See Output
  Connections in the Design Cookbook.

3. Screwy results, particularly with respect to linearity
or high crest factors; differential input application.
 Probably AC-coupled both input pins.
  Solution: Make at least one input DC-coupled. See
Input Connections in the Design Cookbook.

5. Offsets perceived to be out of specification because 0V
in ` 0V out.
   The offsets are not specified at 0V in. No RMS-to-DC
 
  converter works well at 0 due to a divide-by-zero
  calculation.
  Solution: Measure V

.
6. Linearity perceived to be out of specification particularly
with small input signals.
   This could again be due to using 0V in as one of the
  measurement points.
  Solution: Check Linearity from 5mV
RMS
 to 500mV

.
   The input offset voltage can cause small AC
  linearity errors at low input amplitudes as well. See
  Error Analyses section.
  Possible Solution: Include a trim for input offset.
