The MAX7500/MAX7501/MAX7502 is a temperature sensor product of MAXIM company, which uses high-precision, sigma-delta, analog-to-digital converter (ADC) to accurately measure temperature and provide over-temperature alarm/interrupt/shutdown output through the I2C bus interface.
The MAX7500, MAX7501, and MAX7502 are digital temperature sensors that accurately measure temperature and provide an over-temperature alarm or interrupt output. These devices convert temperature measurements to digital form using a high-resolution sigma-delta analog-to-digital converter (ADC) and communicate via an I2C-compatible 2-wire serial interface.
The MAX7500 features three address select lines, while the MAX7501 and MAX7502 feature two address select lines and a RESET input. All devices operate over a supply voltage range of 3.0V to 5.5V with low power consumption.
| Supply Voltage Range | 3.0V to 5.5V |
|---|---|
| Operating Temperature Range | -55°C to +125°C |
| Resolution | 9 Bits |
| Conversion Time | 100 ms |
The typical operating supply current is 250µA.
It integrates a timeout feature that offers protection against I2C bus lockups.
