Maxim Precision Measurement ICs Achieve Double Battery Life for IoT Applications

Article By : Maxim Integrated Products Inc.

Maxim Integrated Products Inc. has launched three new Essential Analog ICs that double the battery life and deliver robust protection and the highest accuracy for industrial and IoT applications.

When designing IoT and battery-operated sensors, engineers must develop systems that provide longer battery life while accurately measuring real-world voltages, forces and pressures. Power budgets require these sensors to achieve precision on the first measurement, with little to no calibration. Furthermore, industrial and Internet of Things (IoT) applications require these sensors to withstand extreme physical conditions of temperature, humidity and mechanical abuse.

To help designers address such challenges, Maxim Integrated Products Inc. has launched three new Essential Analog ICs that double the battery life and deliver robust protection and the highest accuracy for such applications: the MAX41400 instrumentation amplifier, the MAX40108 precision operational amplifier, and the MAX31343 real-time clock (RTC) with integrated MEMS oscillator.

The MAX41400 enhances sensor system accuracy by 4x and extends battery life by 55% compared to the closest competitive offering. It provides low offset of 25µV, low noise and programmable gain with only 65µA current consumption.

The MAX40108 is the lowest-voltage precision operational amplifier in its class, operating with supplies as low as 0.9V. The combination of low operational supply voltage, lower power consumption and 25.5µA quiescent current allows engineers to double sensor battery life.

The MAX31343 I²C RTC with integrated MEMS oscillator provides timekeeping accuracy of ±5ppm, substantially better than the closest competitor, plus robust protection afforded by a MEMS resonator. With its integrated resonator, the MAX31343 eliminates crystal mechanical failures and enables the smallest WLP compared to any other competitor in the market. The innovative packaging scheme, developed by Maxim Integrated, makes this unique combination of size, accuracy and robustness possible.

“These three products represent the best in our Essential Analog offering,” said Vickram Vathulya, vice president of Core Products Group at Maxim Integrated. “Maxim’s mission continues to be providing engineers the finest products to sense and interface with the analog world. These solutions provide superb accuracy and low power consumption for the most demanding sensor applications.”
