Maxim Extends IoT and Sensor Battery Life
Three ultra-small, low-power analog ICs unveiled


Maxim Integrated Korea released three essential analog ICs on the 23rd: the MAX41400 instrumentation amplifier, the MAX40108 precision operational amplifier, and the MAX31343 real-time clock (RTC). These new products implement robust protection features and high accuracy, extending battery life in IoT, industrial, and healthcare applications.

When designing IoT and battery-powered sensors, engineers must develop systems that accurately measure actual voltage, force, and pressure while maintaining a long battery life. To minimize costs, sensors must ensure accuracy upon initial measurement. Furthermore, they must withstand the physical environment, including temperature, humidity, and mechanical abuse, of industrial applications and the IoT.

The MAX41400 instrumentation amplifier consumes only 65µA and combines low 25µV offset, low noise, and programmable gain to increase sensor system accuracy by a factor of four to up to two valid bits. The MAX40108 precision operational amplifier operates from voltages as low as 0.9V and has a quiescent current of 25.5µA.

The MAX31343 I²C RTC features an integrated MEMS oscillator, delivering ±5ppm timekeeping accuracy and less than 3 minutes of annual drift. It eliminates concerns about mechanical crystal failure and offers vibration resistance exceeding 50G. Maxim's three essential analog ICs are available in a variety of small form-factor packages.
