Product Overview
The TMP235 is a Texas Instruments analog output temperature sensor with an output voltage proportional to temperature. For TMP235, the transfer function uses a positive 10 mV/°C slope across -40°C to +150°C and a 500 mV output voltage offset at 0°C. The recommended operating free-air temperature range is -40°C to +150°C, and the operating supply range is 2.3 V to 5.5 V.
Package options include 5-pin SC70 (DCK), 2.00 mm x 1.25 mm, and 3-pin SOT-23 (DBZ), 2.92 mm x 1.30 mm. Pin functions are defined for VDD, VOUT, and GND, with SC70 pins 1 and 5 marked as no internal connection that may be left floating or connected to GND.
Electrical characteristics include 9 µA typical operating current at TA=25°C and VDD=2.3 V, 500 µA maximum output current, 800 µs typical turn-on time to reach accuracy within ±0.5°C, and 1000 pF typical load capacitance. Package thermal resistance values are specified separately for SC70 and SOT-23 designs.

Procurement Notes
When requesting a quote for TMP235, buyers should confirm the manufacturer, package or case, required quantity, target date code, compliance documents, packing method, destination country and expected delivery schedule.
If alternatives are acceptable, buyers should share the approved vendor list, required electrical or optical limits, package constraints and qualification requirements. Any alternative part should be reviewed by the buyer's engineering team before production use.
For analog and signal-chain sourcing, supply voltage, bandwidth, accuracy, noise level, package, temperature grade, input/output configuration and qualification requirements should be verified before approval.
FAQ
What output slope does the TMP235 provide?
The TMP235 provides a positive analog output slope of 10 mV/°C over the -40°C to +150°C temperature range, with a 500 mV output voltage offset at 0°C.
What supply voltage range is specified for TMP235 operation?
The TMP235 operating supply range is 2.3 V to 5.5 V. Its absolute maximum VDD rating is +6 V, which is separate from the recommended operating supply range.
Which packages are listed for the TMP235?
The TMP235 is listed in a 5-pin SC70 DCK package measuring 2.00 mm x 1.25 mm and a 3-pin SOT-23 DBZ package measuring 2.92 mm x 1.30 mm.
What current consumption is specified for the TMP235?
The TMP235 has 9 µA typical operating current at TA=25°C and VDD=2.3 V. Maximum operating current is 14.5 µA from -40°C to +125°C and 17 µA at 150°C.
How are the TMP235 pins assigned?
VDD is the positive supply input, VOUT is the output voltage proportional to temperature, and GND is power supply ground. SC70 pins 1 and 5 are no-connect pins that may float or connect to GND.
