Single-Channel Digital Conversion Module MCP3421 with Positive-and-Negative Input, Four Programmable Options, and Selectable Resolution and Sampling

Features: Selectable Conversion Modes: Choose 18-bit at 3.75 samples per second, 16-bit at 15 samples per second, 14-bit at 60 samples per second, or 12-bit at 240 samples per second to balance finer readings with faster updates. Clearly Organized Connections: Labeled V-, V+, SDA, SCL, GND, and VIN points, a two-position screw terminal, two onboard four-position connectors, and four corner mounting holes. Differential Input Control: The single-channel input measures both polarities, while selectable 1x, 2x, 4x, and 8x amplification settings accommodate different input amplitudes. Transducer and Instrument Applications: Read small-amplitude differential inputs from load cells, pressure transducers, and strain gauges for thermocouple measurement with cold-junction compensation and portable instruments. Package Contents: Includes 1 MCP3421 converter module and 1 pin header.
