CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation
of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
NOTE:
1. θJA is measured with the component mounted on an evaluation PC board in free air.
Electrical Specifications V+ = 9V, TA = 25oC, VREF adjusted for -3.700 reading on DC volts, test circuit as shown in Figure 3.
Crystal = 120kHz. (See Figure 14)

NOTES:
1. Accuracy is defined as the worst case deviation from ideal input value including: offset, linearity, and rollover error.
2. Noise is defined as the width of the uncertainty window (where the display will flicker) between two adjacent codes.
3. Applies to pins 17-20.
4. Analog Common falls out of regulation when the Low Battery Detect is asserted, however the ICL7139 and ICL7149 will continue to
operate correctly with a supply voltage above 7V and below 11V.
5. For 50Hz use a 100kHz crystal.
6. Guaranteed by design, not tested.
7. ICL7139 only.
8. RDG = Reading.
