NOTES: (1) LSB means least significant bit. With V
= +2.5V, one LSB is 610μV. (2) Assured by design, but not tested. Exceeding 50mA source current may result
in device degradation. (3) Difference between TEMP0 and TEMP1 measurement, no calibration necessary. (4) Temperature drift is –2.1mV/°C. (5) TSC2046 operates
down to 2.2V. (6) IOVDD must be - +V
CC
. (7) Combined supply current from +V
CC
and IOVDD. Typical values obtained from conversions on AUX input with
PD0 = 0.
