The LTC2309CUF#PBF from Analog Devices is a versatile, 12-bit analog-to-digital converter featuring 8 multiplexed input channels and an I2C serial interface. With a sampling rate of 14k SPS, it is optimized for precision measurement applications where speed is less critical than accuracy. The device operates from 0°C to +70°C and comes in a compact 24-WFQFN package with an exposed pad for enhanced thermal dissipation. Its two-wire I2C interface simplifies system design and reduces pin count, making it an excellent choice for multi-sensor data acquisition and industrial monitoring.
- 8-Channel Multiplexing: Reduces component count and board space by integrating multiple inputs into one ADC.
- Simple I2C Interface: Only two wires needed for communication, simplifying PCB routing and firmware.
- Compact Package: 24-WFQFN with exposed pad offers a small footprint and good thermal performance.
- Low Power Consumption: Suitable for battery-powered and energy-harvesting applications.
- Flexible Reference: Supports both internal and external references for design flexibility.
