Precision measurement ICs achieve double battery life

25-02-2021 | Maxim | Semiconductors

Creators can now obtain double the battery life together with robust protection and the highest accuracy for IoT, industrial and healthcare applications with three new Essential Analog ICs from Maxim Integrated Products. They now offer the MAX41400 instrumentation amplifier, MAX40108 precision operational amplifier and MAX31343 RTC with integrated MEMS oscillator.

The MAX41400 instrumentation amplifier improves sensor system accuracy by four times and extends battery life by 55% compared to the nearest competitive offering. The device offers low offset of 25µV, low noise and programmable gain with just 65µA current consumption.

The MAX40108 is claimed to be the lowest-voltage precision op-amp in its class, running with supplies as low as 0.9V. The mixture of low operational supply voltage, lower power consumption, and 25.5µA quiescent current enables engineers to double sensor battery life.

The MAX31343 I2C RTC with integrated MEMS oscillator produces a timekeeping accuracy of ±5ppm, considerably better than the nearest competitor, plus robust protection provided by a MEMS resonator. With its integrated resonator, the device removes crystal mechanical failures and allows the smallest WLP compared to any other competitor in the market. The innovative packaging scheme developed by the company makes this unique mixture of size, accuracy and robustness possible.

“The growth of industrial and healthcare IoT applications is driving a growing need for enhanced battery life management and accuracy of measurement to support reduction of power consumption and availability of devices,” said Adam Davidson, analyst at Omdia.

“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.”
