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 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.
