Texas Instruments TMP236A2DCKT

Overview

TMP236A2DCKT 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 output at 0°C. It operates from 3.1 V to 5.5 V supply, draws only 10 µA typical current, and drives capacitive loads up to 1000 pF - ideal for low-power industrial sensing and battery-powered ADC interfaces.

For engineers reviewing the TMP236A2DCKT datasheet, TMP236A2DCKT pinout, TMP236A2DCKT application, or TMP236A2DCKT equivalent, this page delivers verified electrical specs, validated SC70 pin mapping, real-world use cases in grid infrastructure and automotive infotainment, and two confirmed alternative parts with documented functional differences.

Technical Context

The TMP236A2DCKT implements a CMOS-based linear analog temperature transducer with piecewise-linear calibration across three temperature segments (–10°C to 100°C, 100°C to 125°C, and beyond), ensuring ±0.5°C typical accuracy over its full operating range. Its class-AB output driver delivers 500 µA maximum current and maintains stability into 1000 pF loads without external buffering.

Unlike the TMP235, the TMP236 variant uses a higher gain (19.5 mV/°C) and narrower temperature range (–10°C to +125°C), with offset trimmed to 400 mV at 0°C. It requires minimum 3.1 V supply and exhibits <0.1 °C/V line regulation, enabling direct interface to SAR ADC sample-and-hold inputs with minimal error contribution.

FAQ

What is the operating temperature range of the TMP236A2DCKT?

The TMP236A2DCKT operates from –10°C to +125°C with ±0.5°C typical accuracy across that range. It is not specified for operation below –10°C or above +125°C; attempting use outside this range may result in uncharacterized output behavior or reduced accuracy. The device's datasheet explicitly defines its guaranteed performance envelope as –10°C to +125°C, distinct from the wider –40°C to +150°C range of the TMP235 family.

Does the TMP236A2DCKT require external components for basic operation?

Yes - the TMP236A2DCKT requires a 0.1 µF ceramic bypass capacitor placed as close as possible between VDD and GND to ensure stable operation and suppress supply noise. No pull-up/pull-down resistors or output conditioning are needed for standard use, as the device features short-circuit protection and drives 1000 pF loads directly. The NC pins (1 and 5) may be left unconnected or tied to GND.

How does the TMP236A2DCKT differ from the TMP235A2DCKT in practical design?

The TMP236A2DCKT differs from TMP235A2DCKT in three key ways: it has higher sensitivity (19.5 mV/°C vs. 10 mV/°C), narrower temperature range (–10°C to +125°C vs. –40°C to +150°C), and higher minimum supply voltage (3.1 V vs. 2.3 V). These differences make TMP236A2DCKT preferable when resolution and noise margin are critical, while TMP235A2DCKT suits colder environments or lower-voltage systems.

Can the TMP236A2DCKT be used with a 3.3 V microcontroller ADC?

Yes - the TMP236A2DCKT is fully compatible with 3.3 V microcontrollers. Its output spans approximately 0.205 V to 2.838 V across –10°C to +125°C, well within the 0–3.3 V input range of most 3.3 V ADCs. With 19.5 mV/°C gain and 10 µA supply current, it delivers high-resolution thermal data without loading the MCU's power rail or requiring level shifting.

Is the TMP236A2DCKT still in active production?

No - according to Texas Instruments' official orderable addendum, TMP236A2DCKT is marked as "Obsolete" with no active tape-and-reel packaging quantity listed. However, Aetrix Electronics maintains legacy inventory and provides lifecycle coordination support, including cross-reference guidance to active alternatives like TMP236A2DCKR (same SC70-5 package, 3000-piece reel) for ongoing production continuity.
