The LTC1861LCMS#PBF from Analog Devices is a 12-bit, 150k SPS analog-to-digital converter with a 2-channel multiplexer. It features a successive approximation (S/H) architecture and communicates via a simple SPI interface. The device requires an external voltage reference, enabling precise ratiometric measurements. Housed in a compact 10-MSOP package, it operates over a 0°C to 70°C temperature range. Ideal for battery-powered instruments, industrial sensors, and multi-channel data acquisition systems where low power and small size are critical.
- Compact 2-Channel MUX: The integrated 2:1 multiplexer allows sampling two signals without external switching, saving PCB area.
- Low Power for Portable Use: Designed for battery operation, it minimizes current draw while maintaining 150k SPS throughput.
- Simple SPI Interface: The standard 3-wire SPI reduces pin count and simplifies microcontroller integration.
- External Reference Flexibility: Using an external reference enables ratiometric measurements, improving accuracy in bridge sensor applications.
