NOTES
1Including IF noise and using 13 MHz ceramic filter, at VGAIN = 0.2 V.
2Histograms of Demodulator Offset Voltage Variation in Gain and Temperature can be found in Figures 23 to 27.
3Max value represent the value at six times the standard deviation, in the worst case condition (T A = +85°C). The value at three times the standard deviation is 5 µA.
4Max value represent the value at six times the standard deviation. The value at three times the standard variation is 19 mA.
Specifications subject to change without notice.
