NOTES:
1. Integrate time
≥ 66 msec., Auto Zero time ≥ 66 msec., VINT = 4V, VIN = 2.0V Full Scale
Resolution = VINT /integrate time/clock period
2. End point linearity at
±1/4, ±1/2, ±3/4 Full Scale after Full Scale adjustment.
3. Rollover Error also depends on CINT, CREF, CAZ characteristics.
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
sec, 0.54sec, or 1.09sec
which corresponds to clock frequencies of 3.6864 MHz, 1.8432 MHz, 0.9216 MHz respectively.
6. RREF is 100K 1% metal film, 50 ppm/C.
7. Sample tested parameter.
