4 / 17 page LM26NV SNIS151B – AUGUST 2008 – REVISED MARCH 2013 www.ti.com LM26NV Electrical Characteristics The following specifications apply for V + = 2.7V DC to 5.5VDC, and VTEMP load current = 0µA unless otherwise specified. Boldface limits apply for TA = TJ = TMIN to TMAX; all other limits TA = TJ = 25°C unless otherwise specified. LM26NV Limits Symbol Parameter Conditions Typical(1) Units (Limits) (2) Temperature Sensor Trip Point Accuracy (Includes VREF, DAC, -55°C ≤ TA ≤ +110°C ±3 °C (max) Comparator Offset, and Temperature +120°C ±4 °C (max) Sensitivity errors) Trip Point Hysteresis HYST = GND 11 °C HYST = V+ 2 °C IS Supply Current 16 20 µA (max) 40 µA (max) Digital Output and Input IOUT(“1”) Logical “1” Output Leakage Current (3) V+ = +5.0V 0.001 1 µA (max) VOUT(“0”) Logical “0” Output Voltage IOUT = +1.2mA and 0.4 V (max) V+ ≥2.7V; IOUT = +3.2mA and V+ ≥4.5V; (4) VOUT(“1”) Logical “1” Push-Pull Output Voltage ISOURCE = 500µA, V + ≥ 0.8 × V+ V (min) 2.7V ISOURCE = 800µA, V +≥4.5V V+ − 1.5 V (min) VIH HYST Input Logical ”1“ Threshold Voltage 0.8 × V+ V (min) VIL HYST Input Logical ”0“ Threshold Voltage 0.2 × V+ V (max) (1) Typicals are at TJ = TA = 25°C and represent most likely parametric norm. (2) Limits are ensured to AOQL (Average Outgoing Quality Level). (3) The 1µA limit is based on a testing limitation and does not reflect the actual performance of the part. Expect to see a doubling of the current for every 15°C increase in temperature. For example, the 1nA typical current at 25°C would increase to 16nA at 85°C. (4) Care should be taken to include the effects of self heating when setting the maximum output load current. The power dissipation of the LM26NV would increase by 1.28mW when IOUT=3.2mA and VOUT=0.4V. With a thermal resistance of 250°C/W, this power dissipation would cause an increase in the die temperature of about 0.32°C due to self heating. Self heating is not included in the trip point accuracy specification. Package Type θJA SOT-23, DBV 250°C/W Part Number Template The series of characters labeled "xyz" in the part number LM26CIM5-xyz, describe the set point value and the function of the output. The character at "x" and "y" define the set point temperature (at which the digital output will go active). The "z" character defines the type and function of the digital output. These place holders are defined in the following tables. The place holders xy describe the set point temperature as shown in the following table. x (10x) y (1x) Temperature (°C) A - −5 B - −4 C - −3 D - −2 E - −1 F - −0 H H 0 J J 1 K K 2 L L 3 4 Submit Documentation Feedback Copyright © 2008–2013, Texas Instruments Incorporated Product Folder Links: LM26NV |
