NOTES:

1. Integrate time

2. End point linearity at

±1/4, ±1/2, ±3/4 Full Scale after Full Scale adjustment.

4. Contact factory for other power supply operating voltage ranges, including Vsupply =

±3V or Vsupply = ±2.5V.

5. Recommended selection of clock periods of one of the following:

t clk = 0.27

µsec, 0.54µsec, or 1.09µsec

which corresponds to clock frequencies of 3.6864 MHz, 1.8432 MHz, 0.9216 MHz respectively.

7. Sample tested parameter.
