Description
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.
The LM75B can be configured for different operation conditions. It can be set in normal mode to periodically monitor the ambient temperature, or in shutdown mode to minimize power consumption.
FEATURES and BENEFITS
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
