The TMP05/TMP06 are monolithic temperature sensors that
generate a modulated serial digital output (PWM), which varies
in direct proportion to the temperature of the devices. The high
period (TH) of the PWM remains static over all temperatures,
while the low period (TL) varies. The B Grade version offers a
higher temperature accuracy of ±1°C from 0°C to 70°C with
excellent transducer linearity. The digital output of the TMP05/
TMP06 is CMOS/TTL compatible, and is easily interfaced to
the serial inputs of most popular microprocessors. The flexible
open-drain output of the TMP06 is capable of sinking 5 mA.
The TMP05/TMP06 are specified for operation at supply
voltages from 3 V to 5.5 V. Operating at 3.3 V, the supply current
is typically 370 µA. The TMP05/TMP06 are rated for operation
over the –40°C to +150°C temperature range. It is not recom-
mended to operate these devices at temperatures above 125°C
for more than a total of 5% (5,000 hours) of the lifetime of the
devices. They are packaged in low cost, low area SC-70 and
FUNCTIONAL BLOCK DIAGRAM
The TMP05/TMP06 have three modes of operation: continu-
ously converting mode, daisy-chain mode, and one shot mode.
A three-state FUNC input determines the mode in which the
The CONV/IN input pin is used to determine the rate with
which the TMP05/TMP06 measure temperature in continu-
ously converting mode and one shot mode. In daisy-chain
mode, the CONV/IN pin operates as the input to the daisy
1. The TMP05/TMP06 have an on-chip temperature sensor
that allows an accurate measurement of the ambient
temperature. The measurable temperature range is –40°C
2. Supply voltage is 3.0 V to 5.5 V.
3. Space-saving 5-lead SOT-23 and SC-70 packages.
4. Temperature accuracy is typically ±0.5°C. The part needs a
decoupling capacitor to achieve this accuracy.
5. 0.025°C temperature resolution.
6. The TMP05/TMP06 feature a one shot mode that reduces
the average power consumption to 102 µW at 1 SPS.
