(1) LSB means Least Significant Bit. With VREF = +2.5V, one LSB is 610V.
(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 ≤ (+VCC).
(7) Combined supply current from +VCC and IOVDD. Typical values obtained from conversions on AUX input with PD0 = 0.
