ADC and DAC Modules

Extends analog measurement of Arduino boards to 16 bits, for much smoother readings down to ~76uV at 5V. Offers 4 single ended or 2 differential inputs, I2C communication with selectable address, operates at 2-5V and has low power consumption with single shot auto shut-off mode. Ideal for analog sensors and precision data acquisition.

Compact solution for precise measurements of weak analog signals from sensors, load cells or Wheatstone bridges, with 24-bit ADS1256 ADC, up to 30 kSPS and PGA 1-64 for amplification, 8 channels configurable as single-ended or differential, fast data transmission via RS232 DB9 or UART to PC, PLC or development boards, integrated stable 2.5 V reference.

2-channel 4-20mA current acquisition module, ideal for sensor monitoring and integration into industrial automation. Communicates via RS485 Modbus RTU with functions 03 and 06, allows the connection of up to 247 devices on the same network. Provides accurate 1% measurement with 0.1mA resolution and operates at 8-25V for flexible integration.

Quickly convert analog signals to digital data for Arduino and other boards, with 12-bit resolution and up to 860 samples per second via I2C. Offers 4 single-ended or 2 differential inputs, programmable amplifier up to 16X for small signals, low-power 2-5V power supply, and 4 selectable I2C addresses 0x48-0x4B for easy integration.
