GENERAL DESCRIPTION
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° from 01° to 701°, with
excellent transducer linearity. The digital output of the TMP05/
TMP06 is °MOS/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 3 mA.
The °ONV/IN input pin is used to determine the rate with
which the TMP05/TMP06 measure temperature in
continuously converting mode and one shot mode. In
daisy-chain mode, the °ONV/IN pin operates as the input
to the daisy chain.
PRODUCT HIGHLIGHTS
±. The TMP05/TMP06 have an on-chip temperature sensor
that allows an accurate measurement of the ambient
temperature. The measurable temperature range is –401°
to +±501°.
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
(unloaded) is typically 230 µA. The TMP05/TMP06 are rated
for operation over the –401° to +±501° temperature range.
They are packaged in low cost, low area S°-70 and SOT-23
packages.
2. Supply voltage of 3 V to 5.5 V.
3. Space-saving 5-lead SOT-23 and S°-70 packages.
4. Temperature accuracy of ±0.51°.
5. 0.021° temperature resolution.
The TMP05/TMP06 have three modes of operation: continu-
ously converting mode, daisy-chain mode, and one shot mode.
A three-state FUN° input determines the mode in which the
TMP05/TMP06 operate.
6. The TMP05/TMP06 feature a one shot mode that reduces
the power consumption to 2.57 µW at one sample per
second.
