Linear Technology offers eight-channel temperature, voltage and current monitor
Linear Technology
LTC2991
Linear Technology has introduced the LTC2991, an eight-channel I²C temperature, voltage and current monitor for 3V and 5V systems.
The LTC2991 is a highly integrated monitoring system that incorporates a 14-bit ADC, 10ppm/°C voltage reference and I²C digital interface to provide submillivolt voltage resolution and one per cent current measurement, as well as ±0.7°C remote accuracy and ±1°C internal accuracy, when making temperature measurements.
Eight single-ended voltage inputs can be configured to measure any combination of internal temperature, remote temperature, remote voltage and internal VCC for single or repeated measurements.
It is designed for use in a variety of applications, including supply voltage monitoring and remote diode temperature measurement, particularly in industrial or computing systems where thermal management is crucial for maximising performance.
Pricing starts at $4.50 each in 1,000 piece quantities.
