When designing battery-powered IoT sensors, engineers must develop systems that provide extended battery life while accurately measuring real-world voltages, forces, and pressures. Power constraints demand that these sensors achieve first-time accuracy with little to no calibration. Furthermore, industrial and IoT applications require these sensors to withstand extreme physical conditions of temperature, humidity, and mechanical stress.
Maxim Integrated's new essential analog precision measurement integrated circuits:
The MAX41400 instrumentation amplifier improves sensor system accuracy by 4x and extends battery life by 55% compared to the closest competitor offering. The MAX41400 provides a low offset of 25µV, low noise, and programmable gain with only 65µA of current draw. The MAX40108
is the lowest-voltage precision operational amplifier in its class, operating from supplies as low as 0.9V. The combination of a low operating supply voltage, lower power consumption, and a quiescent current of 25.5µA allows engineers to double sensor battery life.
The MAX31343 I²C RTC with integrated MEMS oscillator provides ±5ppm timing accuracy, substantially better than the closest competitor, along with robust protection provided by a MEMS resonator. With its integrated resonator, the MAX31343 eliminates mechanical crystal failures and enables the smallest WLP compared to any competitor on the market. The innovative packaging design, developed by Maxim Integrated, makes this unique combination of size, precision, and robustness possible. All of these products offer multiple package options and small form factor configurations.
Key Benefits
: Longer Battery Life: The MAX40108 precision operational amplifier doubles the sensor's battery life when operating at 0.9V, compared to the closest competitor offering at 1.8V. For battery-powered industrial sensors, the MAX41400 extends battery life from the existing 7.4 hours to 11.5 hours, compared to the closest competitor offering.
Maximum Accuracy: The MAX31343 provides the highest timing accuracy, guaranteeing minimal deviation.
Robust Protection: Along with its nanoPower features and high accuracy, the MAX31343 also offers shock resistance of >2900G and vibration resistance of >50G. Maxim Integrated is the only RTC supplier offering this level of robust protection on the market.
