The LM75B is a temperature-to-digital converter using an on-chip band gap temperature sensor and Sigma-Delta A-to-D conversion technique with an overtemperature detection output.

Pin-for-pin replacement for industry standard LM75 and LM75A and offers improved temperature resolution of 0.125 C and specification of a single part over power supply range from 2.8 V to 5.5 V I2C-bus interface with up to 8 devices on the same bus
 Power supply range from 2.8 V to 5.5 V
 Temperatures range from 55 C to +125 C

 Frequency range 20 Hz to 400 kHz with bus fault time-out to prevent hanging up the bus
 11-bit ADC that offers a temperature resolution of 0.125 C
 Programmable temperature threshold and hysteresis set points
 Supply current of 1.0 A in shutdown mode for power conservation
 Stand-alone operation as thermostat at power-up

Applications
 System thermal management
 Personal computers
