Rutronik adds the low power IC NJU9101 from JRC to its portfolio

Distributor Rutronik presents the low power Analog Front End (AFE) NJU9101 from New Japan Radio (JRC). It is designed for portable measurement equipment and for use in micro-power sensing applications, especially electrochemical sensors.

Two measurement inputs, potentiostat and auxiliary, enable a broad range of measurement in portable devices. Using 3-Bit chip address function the AFE chip can detect up to seven different types of electrochemical gases by only one sensor.

The NJU9101 provides a complete signal processing solution between sensor and micro-processor as smart-sensor module. The AFE converts a sensor signal into the signal that an MCU or an external EEPROM can process. It also integrates a sensor diagnostic function. The NJU9101 operates over voltage ranges of 2.4V to 3.6V. Its total average current consumption can be less than 5μA. In stand-by mode, the current consumption is 0.5μA, so the power consumption is as low as possible in order to ensure a long battery life. Also the precision, low noise operational amplifiers inside NJU9101 and the high precision delta-sigma 16bit A/D converter are designed to consume less power. This high resolution ADC has a programmable gain of 1V/V to 8V/V, 16-Bit and a sample rate of 32sps to 2ksps. The built-in operational amplifiers are immune to RF noise from for example GSM, 3G, Bluetooth, W-LAN for transceiver (150MHz, 5W) which prevent the AFE from malfunction. The operating temperature is between -40°C to +85°C. It comes in the small package EQFN-24-LE (4mm x 4mm).

The NJU9101 is perfect for use in portable devices and applications like Gas Monitor, Blood Glucose Meter, Current Sensing Systems, Low Power Systems and Photodiode Sensing Systems.
