A class-AB output structure gives the LMT84/LMT84Q1 strong output source and sink current capability for driving heavy loads. This means it is well suited to source the input of a sample-and-hold analog-todigital converter with its transient load requirements. While operating over the wide temperature range of −50°C to 150°C, the LMT84/LMT84-Q1 deliver an output voltage that is inversely proportional to measured temperature. The LMT84/LMT84-Q1 low supply current make it ideal for battery-powered systems as well as general temperature sensing applications. 1 2 • • • • • • • • LMT84-Q1 is AEC-Q100 Grade 0 qualified and is Manufactured on an Automotive Grade Flow Low 1.5 V Operation Push-Pull Output with 50 µA Source Current Capability Very Accurate Over Wide Temperature Range of −50°C to 150°C Low Quiescent Current Output is Short-Circuit Protected Extremely Small SC70 Package Footprint Compatible with the IndustryStandard LM20 Temperature Sensor Cost-effective Alternative to Thermistors APPLICATIONS • • • • • • • • • Automotive Industrial White Goods Battery Management Disk Drives Appliances Games Wireless Transceivers Cell phones The LMT84/LMT84-Q1 alternatives to thermistors.

This shape is very accurately reflected in Table 1. The Transfer Table can be calculated by using the parabolic equation. mV mV ª º ª 2º VTEMP mV = 870.6mV - «5.506 T - 30°C » - «0.00176 2 T - 30°C » °C ¬ ¼ ¬ °C ¼ (1) For a linear approximation, a line can easily be calculated over the desired temperature range from the Table using the two-point equation: · ¹ V - V1 = V2 - V1 T2 - T1 · u (T - T1) ¹ (2) Where V is in mV, T is in °C, T1 and V1 are the coordinates of the lowest temperature, T2 and V2 are the coordinates of the highest temperature. For example, if we want to resolve this equation, over a temperature range of 20°C to 50°C, we would proceed as follows: 760 mV - 925 mV · u (T - 20oC) 50oC - 20oC ¹ · ¹ V - 925 mV = (3) o o V - 925 mV = (-5.50 mV / C) u (T - 20 C) (4) o V = (-5.50 mV / C) u T + 1035 mV (5) Using this method of linear approximation, the transfer function can be approximated for one or more temperature ranges of interest. MOUNTING AND THERMAL CONDUCTIVITY The LMT84/LMT84-Q1 can be applied easily in the same way as other integrated-circuit temperature sensors. It can be glued or cemented to a surface. To ensure good thermal conductivity, the backside of the LMT84/LMT84-Q1 die is directly attached to the GND pin (Pin 2). The temperatures of the lands and traces to the other leads of the LMT84/LMT84-Q1 will also affect the temperature reading. Alternatively, the LMT84/LMT84-Q1 can be mounted inside a sealed-end metal tube, and can then be dipped into a bath or screwed into a threaded hole in a tank. As with any IC, the LMT84/LMT84-Q1 and accompanying wiring and circuits must be kept insulated and dry, to avoid leakage and corrosion. This is especially true if the circuit may operate at cold temperatures where condensation can occur. If moisture creates a short circuit from the output to ground or VDD, the output from the LMT84/LMT84-Q1 will not be correct. Printed-circuit coatings are often used to ensure that moisture cannot corrode the leads or circuit traces. The thermal resistance junction to ambient (θJA) is the parameter used to calculate the rise of a device junction temperature due to its power dissipation. The equation used to calculate the rise in the LMT84/LMT84-Q1's die temperature is: TJ = TA + TJA ¬ª(VDDIS ) + (VDD - VO ) IL ¼º (6) where TA is the ambient temperature, IS is the supply current, ILis the load current on the output, and VO is the output voltage. For example, in an application where TA = 30°C, VDD = 5 V, IS = 5.4 μA, VOUT = 871 mV, and IL = 2 μA, the junction temperature would be 30.0146°C, showing a self-heating error of only 0.014°C. Since the LMT84/LMT84-Q1's junction temperature is the actual temperature being measured, care should be taken to minimize the load current that the LMT84/LMT84-Q1 is required to drive. Table 2 shows the thermal resistance of the LMT84/LMT84-Q1. Table 2.

This is beneficial when, for example, driving dynamic loads like an input stage on an analog-to-digital converter (ADC). In these applications the source current is required to quickly charge the input capacitor of the ADC. See the APPLICATION CIRCUITS section for more discussion of this topic. The LMT84/LMT84-Q1 is ideal for this and other applications which require strong source or sink current. The LMT84/LMT84-Q1 supply-noise gain (the ratio of the AC signal on VOUT to the AC signal on VDD) was measured during bench tests. Its typical attenuation is shown in the TYPICAL PERFORMANCE CHARACTERISTICS section. A load capacitor on the output can help to filter noise. For operation in very noisy environments, some bypass capacitance should be present on the supply within approximately 5 centimeters of the LMT84/LMT84-Q1. CAPACITIVE LOADS The LMT84/LMT84-Q1 handles capacitive loading well. In an extremely noisy environment, or when driving a switched sampling input on an ADC, it may be necessary to add some filtering to minimize noise coupling. Without any precautions, the LMT84/LMT84-Q1 can drive a capacitive load less than or equal to 1100 pF as shown in Figure 11. For capacitive loads greater than 1100 pF, a series resistor may be required on the output, as shown in Figure 12. VDD LMT84 OPTIONAL BYPASS CAPACITANCE OUT GND CLOAD ” 1100 pF Figure 11.

Due to the intrinsic behavior of an NMOS/PMOS rail-to-rail buffer, a slight shift in the output can occur when the supply voltage is ramped over the operating range of the device. The location of the shift is determined by the relative levels of VDD and VOUT. The shift typically occurs when VDD- VOUT = 1.0V. This slight shift (a few millivolts) takes place over a wide change (approximately 200 mV) in VDD or VOUT. Since the shift takes place over a wide temperature change of 5°C to 20°C, VOUT is always monotonic. The accuracy specifications in the ELECTRICAL CHARACTERISTICS table already include this possible shift.

When the ADC charges the sampling cap, it requires instantaneous charge from the output of the analog source such as the LMT84/LMT84-Q1 temperature sensor and many op amps. This requirement is easily accommodated by the addition of a capacitor (CFILTER). The size of CFILTER depends on the size of the sampling capacitor and the sampling frequency. Since not all ADCs have identical input stages, the charge requirements will vary. This general ADC application is shown as an example only. Figure 15.

TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily performed. TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide adequate design and operating safeguards. TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the third party, or a license from TI under the patents or other intellectual property of TI. Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional restrictions. Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements. Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use of any TI components in safety-critical applications. In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and requirements. Nonetheless, such components are subject to these terms. No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties have executed a special agreement specifically governing such use. Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and regulatory requirements in connection with such use. TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
