PCT2075 - digital temperature sensor

General Description

The PCT2075 is a temperature-to-digital converter featuring ±1 °C accuracy over -25 °C to +100 °C range.

Key Features

  • Pin-for-pin replacement for LM75 series but allows up to 27 devices on the bus.
  • Power supply range from 2.7 V to 5.5 V.
  • SDA and SCL inputs are overvoltage tolerant to 5.5 V NXP Semiconductors PCT2075 I2C-bus Fm+, 1 °C accuracy, digital temperature sensor and thermal watchdog.
  • SDA and OS open drain outputs can be pulled up to 5.5 V regardless of supply voltage.
  • Temperatures range from -55 °C to +125 °C.
  • Frequency range 20 kHz to 1 MHz wit.
