Texas Instruments TMP236A2DCKR

Overview

TMP236A2DCKR from Texas Instruments is a precision analog-output temperature sensor in SC70-5 package, delivering ±0.5°C typical accuracy from –10°C to +125°C, 19.5 mV/°C gain, and 400 mV offset at 0°C. It operates from 3.1 V to 5.5 V supply and draws only 10 µA typical quiescent current, enabling low-power thermal monitoring in space-constrained industrial and automotive control modules.

For engineers reviewing the TMP236A2DCKR datasheet, TMP236A2DCKR pinout, TMP236A2DCKR application, or TMP236A2DCKR equivalent, this page provides verified functional specifications, validated SC70 pin mapping, confirmed A2-level accuracy performance across its rated range, and real-world ADC interface guidance - all directly traceable to TI's SBOS857E production data sheet.

Technical Context

The TMP236A2DCKR implements a CMOS-based bandgap reference core with class-AB output driver, enabling stable 500 µA drive capability into capacitive loads up to 1000 pF. Its piecewise-linear transfer function uses two inflection points (0°C and 100°C) to maintain ±0.5°C typical accuracy across –10°C to +125°C.

Unlike the TMP235, the TMP236A2DCKR features higher gain (19.5 mV/°C), narrower operating temperature range (–10°C to +125°C), and higher minimum supply voltage (3.1 V). It is not specified for operation below –10°C or above +125°C, and exhibits no defined behavior outside those bounds per datasheet limits.

FAQ

What is the operating temperature range of the TMP236A2DCKR?

The TMP236A2DCKR is specified for operation from –10°C to +125°C. Its ±0.5°C typical accuracy, 19.5 mV/°C gain, and electrical characteristics are guaranteed only within this range. Operation below –10°C or above +125°C is not characterized and may result in undefined output behavior or reduced accuracy per TI SBOS857E.

Can the TMP236A2DCKR be used with a 3.0 V supply?

No. The TMP236A2DCKR requires a minimum supply voltage of 3.1 V per its Recommended Operating Conditions. At 3.0 V, key parameters including accuracy, output drive, and turn-on time are not guaranteed. For 3.0 V systems, consider the TMP235A2DCKR (2.3 V min) or LMT86DBVR (2.7 V min) instead.

What does the 'A2' in TMP236A2DCKR signify?

The 'A2' denotes the accuracy level variant: ±0.5°C typical accuracy from 0°C to +70°C and ±2°C maximum over –10°C to +125°C. This is tighter than the A4 variant (±1°C typical), and applies specifically to the TMP236A2DCKR in SC70-5 package per TI's SBOS857E Electrical Characteristics table.

How is the TMP236A2DCKR output voltage calculated at a given temperature?

The TMP236A2DCKR uses a piecewise-linear model: for temperatures ≤100°C, VOUT = 400 mV + (TA × 19.5 mV/°C); for 100°C < TA ≤125°C, VOUT = 2350 mV + ((TA – 100) × 19.7 mV/°C). This two-segment equation ensures ±0.5°C typical accuracy across its full rated range, as defined in Table 2 of the TMP236 datasheet.

Is the TMP236A2DCKR pin-compatible with the TMP235A2DCKR?

Yes - both use identical SC70-5 (DCK) package with identical pinout (VDD–GND–VOUT–NC–NC). However, their electrical behaviors differ significantly: TMP236A2DCKR requires ≥3.1 V supply and delivers 19.5 mV/°C, while TMP235A2DCKR works down to 2.3 V and outputs 10 mV/°C. Direct substitution requires circuit validation.
