(2) For information on self-heating and thermal response time see Layout Guidelines section.
(3) The junction to ambient thermal resistance (RθJA ) under natural convection is obtained in a simulation on a JEDEC-standard, High-K
board as specified in JESD51-7, in an environment described in JESD51-2. Exposed pad packages assume that thermal vias are
included in the PCB, per JESD 51-5.
(4) Changes in output due to self heating can be computed by multiplying the internal dissipation by the thermal resistance.

7 Detailed Description
7.1 Overview
The TMP23x devices are a family of linear analog temperature sensors with an output voltage proportional to
temperature. These temperature sensors have an accuracy from 0°C to 70°C of ±1.25°C (TMP23xA2) and ±2°C
(TMP23xA4). The TMP235 device provides a positive slope output of 10 mV/°C over the full –40°C to +150°C
temperature range and a supply range from 2.3 V to 5.5 V. The higher gain TMP236 sensor provides a positive
slope output of 19.5 mV/°C from –10°C to +125°C and a supply range from 3.1 V to 5.5 V. A class-AB output
driver provides a maximum output of 500 µA to drive capacitive loads up to 1000 pF.

7.3 Feature Description
As shown in 图 3, the TMP23x devices are linear. A small VOUT gain shift, however, is present at temperatures
above 100°C. When small shifts are expected, a piecewise linear function provides the best accuracy and is
used for the device accuracy specifications (see Specifications). Typical output voltages of the TMP23x devices
across the full operating temperature range are listed in 表 3 and 表 4. The ideal linear columns represent the
ideal linear VOUT output response with respect to temperature, while the piecewise linear columns indicate the
small voltage shift at elevated temperatures.
The piecewise linear function uses three temperature ranges listed in 表 1 and 表 2. In equation form, the voltage
output VOUT of the TMP23x is calculated by 公式 1:
VOUT = (TA – TINFL) × TC + VOFFS
where
•
•
•
•
•
VOUT is the TMP23x voltage output for a given temperature
TA is the ambient temperature in °C
TINFL is the temperature inflection point for a piecewise segment in °C
TC is the TMP23x temperature coefficient or gain
VOFFS is the TMP23x voltage offset
(1)
Therefore, the TA temperature for a given VOUT voltage output within a piecewise voltage range (VRANGE) is
calculated in 公式 2. For applications where the accuracy enhancement above 100°C is not required, use the first
row of 表 1 and 表 2 for all voltages.
TA = (VOUT – VOFFS ) / TC + TINFL

8 Application and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
8.1 Application Information
The features of the TMP235 make the series of devices designed for various general temperature-sensing
applications. The TMP235 and TMP236 devices can operate down to a 2.3-V and a 3.1-V supply with 9-µA
power consumption, respectively. As a result, the series is designed for battery-powered applications. The
TMP23x series is mounted in two surface mount technology packages (SC70 and SOT-23.)

Figure 13. Suggested Connections to an ADC Input Stage
8.2.1.1 Design Requirements
See Figure 13 for suggested connections to an ADC input stage. Most CMOS-based ADCs have a sampled data
comparator input structure. When the ADC charges the sampling capacitor (CSAMPLE), the capacitor requires
instantaneous charge from the output of the analog source temperature sensor, such as the TMP23x. Therefore,
the output impedance of the temperature sensor can affect ADC performance. In most cases, adding an external
capacitor (CFILTER) mitigates design challenges. The TMP23x is specified and characterized with a 1000-pF
maximum capacitive load (CLOAD). Figure 13 shows CLOAD as the sum of CFILTER + CMUX + CSAMPLE. TI
recommends maximizing the CFILTER value while allowing for the maximum specified ADC input capacitance
(CMUX + CSAMPLE) to limit the total CLOAD at 1000 pF. In most cases, a 680-pF CFILTER provides a reasonable
allowance for ADC input capacitance to minimize ADC sampling error and reduce noise coupling. An optional
series resistor (RFILTER) and CFILTER provides additional low-pass filtering to reject system level noise. TI
recommends placing RFILTER and CFILTER as close as possible to the ADC input for optimal performance.
8.2.1.2 Detailed Design Procedure
Depending on the input characteristics of the ADC, an external CFILTER may be required. The value of CFILTER
depends on the size of the sampling capacitor (CSAMPLE) and the sampling frequency while observing a maximum
CLOAD of 1000 pF. The capacitor requirements can vary because the input stages of all ADCs are not identical.
Figure 13 shows a general ADC application as an example only.

9 Power Supply Recommendations
The low supply current and supply range of the TMP23x allow the device to be easily powered from many
sources.
Power supply bypassing is strongly recommended. In noisy environments, TI recommends to add a filter with
0.1-μF capacitor and 100-Ω resistor between external supply and VDD to limit the power supply noise. Larger
capacitances may be required and are dependent on the noise of the power supply.
10 Layout
10.1 Layout Guidelines
The layout of the TMP23x series is simple. If a power supply bypass capacitor is used, the capacitor must be
connected as Layout Examples shows.
