PCF8591T 8‑Bit A/D and D/A Converter IC SOP‑16 Single‑Chip CMOS Data Acquisition Chip Low Power For Analog Signal Conversion

PCF8591T 8‑Bit A/D and D/A Converter IC

📌 Product Overview PCF8591T is a single‑chip, independent power supply, low‑power 8‑bit CMOS data acquisition device packaged in SOP‑16. It integrates 4 programmable analog input channels, 1 analog output channel and a two‑wire I2C serial communication interface. Three hardware address pins allow up to 8 chips to run on the same I2C bus without extra peripheral circuits. All control and data signals are transmitted through the bidirectional I2C bus, which is widely used for analog signal collection and digital‑to‑analog conversion in embedded control projects. ✨ Core Features

• Independent power supply design
• Wide operating voltage: 2.5V‑6V
• Ultra‑low standby current
• Data transmission via standard I2C bus
• 3 hardware address pins for multi‑device stacking
• Sampling speed controlled by I2C communication rate
• 4 analog inputs configurable for single‑ended or differential mode
• Automatic incremental channel switching function
• Analog input range: VSS to VDD
• Built‑in track‑and‑hold circuit
• 8‑bit successive‑approximation analog‑to‑digital converter
• 1 channel of 8‑bit digital‑to‑analog output for DAC gain adjustment

📐 Dimension Info Package Type: SOP‑16 Pin Count: 16 pins ⚠ Important Usage Notice EXT pin connects to GND when using the internal clock source. Multiple PCF8591T chips on one I2C bus require different hardware address settings via A0, A1, A2 pins. 🛠 Application Scenarios Analog signal acquisition, sensor data sampling, PWM analog output control, microcontroller peripheral expansion, industrial detection modules, DIY electronic projects.
