This PCF8591 module is a monolithically integrated, low-power, 8-bit CMOS data acquisition device. The PCF8591 has four analog inputs, one analog output and a serial I2C bus interface. For testing purposes, the module contains a phototransistor, NTC and a trimmer which are connected to the PCF8591 by 3 jumpers.
Features:

1. single power supply
2. operating supply voltage 2.5 V to 6.0 V
3. low standby current
4. serial input and output via I2C-bus
5. max sampling rate given by I2C-bus speed
6. 4 analog inputs configurable as single ended or differential inputs
7. auto-incremented channel selection
8. analog voltage range from VSS to VDD
9. on-chip track and hold circuit
10. 8-bit successive approximation A/D conversion
11. multiplying DAC with one analog output
