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:
- Single power supply
- Low standby current
- Serial input and output via I2C-bus
- Max sampling rate given by I2C-bus speed
- 4 analog inputs configurable as single ended or differential inputs
- Auto-incremented channel selection
- Analog voltage range from VSS to VDD
- On-chip track and hold circuit
- 8-bit successive approximation A/D conversion
- Multiplying DAC with one analog output
Specifications:
- Operating supply voltage: 2.5-6.0 V
