GND ...-0.3V to VDD +0.3V Storage temperature .......................... -65°C to +150°C Ambient temp. with power applied ..... -55°C to +125°C Junction Temperature ........................................ 150°C ESD protection on all pins: Human Body Model (HBM)............................. > 4 kV Man Machine Model (MM)............................. > 400V Latch-Up Current at each pin ........................ ±200 mA Maximum Power Dissipation........................... 250 mW † Notice: Stresses above those listed under "Maximum Ratings" may cause permanent damage to the device. This is a stress rating only and functional operation of the device at those or any other conditions above those indicated in the operation listings of this specification is not implied. Exposure to maximum rating conditions for extended periods may affect device reliability. PIN FUNCTION TABLE Name Function NC No Internal Connection CE Chip Enable Input, the device is selected when this input is high SCK Serial Clock Input GND Ground SDO Serial Data Output SDI Serial Data Input NC No Internal Connection VDD Power Supply DC CHARACTERISTICS Electrical Specifications: Unless otherwise noted, all parameters apply at V DD = 2.65V to 5.5V, T A = -55°C to +125 °C. Parameters Sym Min Typ Max Units Conditions Power Supply Operating Voltage Range VDD 2.65 — 5.5 V Note 1 Operating Current: Normal Mode, ADC Active IDD-CON — 250 400 µA Continuous temp. conversion mode (Shutdown Bit = ‘0’) Shut-Down Supply Current ISHD — 0.1 1.0 µA Shutdown Mode (Shutdown Bit = ‘1’) Temperature Sensor and Analog-to-Digital Converter Temperature Accuracy (Note 1) TACY -2.0 — +2.0 °C -40°C < TA < +85°C -3.0 — +3.0 -55°C < TA < +125°C Resolution — 10 — Bits Note 4 ADC Conversion Time tCONV —150 200 ms Digital Input / Output High Level Input Voltage VIH 0.7 VDD —— V Low Level Input Voltage VIL — — 0.2 VDD V High Level Output Voltage VOH 0.7 VDD —— V IOH = 1 mA Low Level Output Voltage VOL — — 0.2 VDD VIOL = 4 mA Input Resistance RIN 1.0 — — M Ω Pin Capacitance CIN —15 — pF COUT —50 — Note 1: The TC72-2.8MXX, TC72-3.3MXX and TC72-5.0MXX will operate from a supply voltage of 2.65V to 5.5V. However, the TC72-2.8MXX, TC72-3.3MXX and TC72-5.0MXX are tested and specified at the nominal operating voltages of 2.8V, 3.3V and 5.0V respectively. As VDD varies from the nominal operating value, the accuracy may be degraded. Refer to Figure 2-5 and Figure 2-6. 2: Measured with a load of CL = 50 pF on the SDO output pin of the TC72. 3: All time measurements are measured with respect to the 50% point of the signal, except for the SCK rise and fall times. The rise and fall times are defined as the 10% to 90% transition time. 4: Resolution = Temperature Range/No. of Bits = (+127°C – -128°C) / (210) = 256/1024 = 0.25°C/Bit |
