The PCF8591 is a single-chip, single-supply and low-power 8-bit CMOS data acquisition device with four analog inputs, one analog output and a serial I2C-bus interface. Three address pins A0, A1 and A2 are used for programming the hardware address, allowing maximum of eight devices connected to the I2C-bus without additional hardware. Address, control and data to and from the device are transferred serially via the two-line bidirectional I2C-bus.

Single supply, low standby current
Address by 3 hardware address pins
Sampling rate is given by I2C-bus speed
4 analog inputs programmable as single-ended or differential inputs
Auto-incremented channel selection
Analog voltage range from VSS to VDD
On-chip track and hold circuit
Multiplying DAC with one analog output

Good converter By Hobert 2019-12-17 10:39:10

I've purchased a few of these in the past and can easily tell if the converter is good or not. The quality on this one is quite good, especially for the price. It's simple to use and is exactly what I expected.
