7 / 60 page  TDC1000, TDC1000-Q1 www.ti.com SNAS648B – OCTOBER 2014 – REVISED AUGUST 2015 Electrical Characteristics (continued) The electrical ratings specified in this section apply to all specifications in this document, unless otherwise noted. These specifications are interpreted as conditions that do not degrade the device parametric or functional specifications for the life of the product containing it. TA = 25°C, VDD = VIO = 3.7 V, VCOM = VCM = VDD / 2, CVCOM = 10 nF (unless otherwise noted).

(3) With ideal external components. For more detail see Temp Sensor Measurement section. (4) PT1000 RTD approximate resistance: 800 Ω ≡ –52°C, 931 Ω ≡ –18°C, 1.10 kΩ ≡ 26°C, 1.33 kΩ ≡ 86°C and 1.48 kΩ ≡ 125°C. (5) Specified currents include 120 μA which flows through the RTD sensor in PT1000 mode (TEMP_RTD_SEL = 0). (6) Specified currents include 240 μA which flows through the RTD sensor in PT500 mode (TEMP_RTD_SEL = 1).
