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 (T
while the low period (T
high 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
SOT-23 packages.
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
TMP05/TMP06 operate.
The CONV/IN input pin is used to determine the rate at which
the TMP05/TMP06 measure temperature in continuously
converting mode and one shot mode. In daisy-chain mode, the
CONV/IN pin operates as the input to the daisy chain.

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 to +150°C.
Supply voltage is 3 V to 5.5 V.
Space-saving 5-lead SOT-23 and SC-70 packages.
Temperature accuracy is typically ±0.5°C. Each part needs
a decoupling capacitor to achieve this accuracy.
Temperature resolution of 0.025°C.
The TMP05/TMP06 feature a one shot mode that reduces
the average power consumption to 102 μW at 1 SPS.
