3 Description

The TMP461-SP device is a radiation-hardened,

high-accuracy, low-power remote temperature sensor

monitor with a built-in local temperature sensor. The

remote temperature sensors are typically low-cost

discrete NPN or PNP transistors, or substrate thermal

transistors or diodes that are integral parts of

microprocessors, analog-to-digital converters (ADC),

digital-to-analog converters (DAC), microcontrollers,

or field-programmable gate arrays (FPGA).

Temperature is represented as a 12-bit digital code

for both local and remote sensors, giving a resolution

of 0.0625°C. The two-wire serial interface accepts the

SMBus communication protocol with up to nine

different pin-programmable addresses.

Advanced features such as series resistance

cancellation, programmable nonideality factor (η-

factor), programmable offset, programmable

temperature limits, and a programmable digital filter,

are combined to provide a robust thermal monitoring

solution with improved accuracy and noise immunity.

The TMP461-SP is ideal for multi-location, highaccuracy

temperature measurements in a variety of

distributed telemetry applications. The integrated

local and remote temperature sensors simplify

spacecraft housekeeping activities by providing an

easy way of measuring temperature gradients. The

device is specified for operation over a supply voltage

range of 1.7 V to 3.6 V, and a temperature range of

–55°C to 125°C.
