The BOKRA I2C 8AI LTC2309 modules are analog input modules based on the 12-bit high-speed and low-power ADC LTC2309. The modules allow you to measure eight differential analog signals - both voltage and current. Compatible with Rapberry, Arduino, Nucleo, Adafruit, Teensy and most types of microcontrollers (I2C interface is used to communicate with them).

Used in the Analog Devices LTC2309 ADC module, it has 12 bits. The type of ADC used is SAR (sequential approximation ADC). Measurement speed - 14000 measurements per second. The range of voltage measurement is 0-5V. Measuring Current Range: 4-20mA. The ADC used in the module is characterized by low consumption: 1.5mW for a speed of 1000 measurements per second, 35μW in Sleep mode.

Input power: 5VDC. Possibility of using internal and external reference voltage.

The BOKRA I2C 8AI LTC2309 module size 65 x 56 mm. The format of the module corresponds to the popular format of the Raspberry Pi 3A+, which greatly simplifies its use with the Raspberry Pi.
