Product Description
PCF8591 AD / DA chip introduced
PCF8591 is a monolithic, single supply, low-power, 8-bit CMOS data acquisition devices. PCF8591 has 4 analog inputs, one analog output and a serial I2C bus interface. PCF8591 of three address pins A0, A1 and A2 can be used for programming the hardware address, allowing access to eight PCF8591 devices on the same I2C-bus, without the need for additional hardware. Input and output on the PCF8591 device address, control and data signals through two-line bidirectional I2C bus serially transmitted.
PCF8591 Key performance indicators:
single power supply
PCF8591 operating voltage range of 2.5V-6V
Low Standby Current
via I2C-bus serial input / output
PCF8591 by 3 hardware address pins addressing
PCF8591 I2C bus speed sampling rate decision
4 programmable analog inputs for single-ended or differential inputs
auto increment channel selection
PCF8591 analog voltage range from VSS to VDD
PCF8591 built-in track and hold circuit
8-bit successive approximation A / D converter
DAC gain realized by an analog output
Two baby description
A module chip PCF8951
2 module supports four external voltage input acquisition (voltage input range 0-5v)
3 modules integrated photoresistor, you can collect the ambient light intensity AD exact numeric
4 modules integrated thermistor, you can collect the ambient temperature exact numeric AD
5 module integrates a road 0-5V voltage input acquisition (via the blue potentiometer to adjust the input voltage)
6 modules with power indicator (on the module power indicator will light)
7 modules with DA output indicator, when the module DA output interface voltage reaches a certain value, it will light up the board DA output indicator, the greater the voltage, the LED brightness is more obvious;
