Typical Application (continued)

8.2.3 Application Curve

Figure 19 shows the typical step response to submerging a sensor in an oil bath with a temperature of 100°C.

8.3 Radiation Environments

Careful consideration should be given to environmental conditions when using a product in a radiation

environment.

8.3.1 Single Event Latch-Up

One-time single event latch-up (SEL) testing was preformed according to EIA/JEDEC Standard, EIA/JEDEC57.

The linear energy transfer threshold (LETth) shown in Features is the maximum LET tested. A test report is

available upon request.

8.3.2 Single Event Functional Interrupt

To mitigate effects of single-event upsets and single-event functional interrupts, it is recommended that

appropriate value be written to the pointer register each time a read operation is performed. Relying on the last

value stored in the pointer register may increase the probability of a failed read due to a single event upset.

If other functions are being used, such as the temperature limit register, it may be necessary to rewrite these

registers on occasion.

8.3.3 Single Event Upset

A report on single event upset (SEU) is available upon request.

9 Power Supply Recommendations

The TMP461-SP device operates with a power-supply range of 1.7 V to 3.6 V. The device is optimized for

operation at a 3.3-V supply but can measure temperature accurately in the full supply range.

A power-supply bypass capacitor is recommended. Place this capacitor as close as possible to the supply and

ground pins of the device. A typical value for this supply bypass capacitor is 0.1 μF. Applications with noisy or

high-impedance power supplies may require additional decoupling capacitors to reject power-supply noise.
