Applications
MCP3424-E/ST is used in precision industrial and scientific measurement systems where 18-bit resolution is required to resolve small differential signals from bridge sensors, thermocouples, and pressure transducers. Its I2C interface allows multiple ADC devices to share a single 2-wire bus, enabling scalable multi-channel data acquisition with minimal wiring. The integrated programmable gain amplifier further extends usable input range to amplify millivolt-level signals before conversion.

Frequently Asked Questions
What resolution and linearity does MCP3424-E/ST achieve, and how does that benefit precision sensor measurements?
MCP3424-E/ST provides 18-bit resolution with a maximum linearity error of 0.0035%, corresponding to roughly 1 LSB of integral nonlinearity across its ±2.048 V input range. This level of accuracy is critical for bridge-type sensors such as load cells and pressure transducers, where even a few microvolts of offset or nonlinearity can translate to measurable errors in final physical units.
How many differential channels does MCP3424-E/ST provide, and can multiple devices share a single I2C bus?
MCP3424-E/ST has 4 differential input channels, each accepting signals up to ±2.048 V. Up to 8 MCP3424 devices can be connected on a single I2C bus by using address pins to assign unique 7-bit addresses, enabling a 32-channel differential measurement system without additional multiplexers, which simplifies wiring in multi-sensor industrial and laboratory data acquisition setups.
For a bridge-sensor application with a 10 mV full-scale output, how should the MCP3424-E/ST programmable gain be configured?
With a 10 mV full-scale sensor output and an ADC input range of ±2.048 V, the internal programmable gain amplifier should be set to 128 V/V, which scales the 10 mV signal to approximately ±1.28 V at the ADC input, using about 63% of the full-scale range. This maximizes dynamic range without saturating the converter, and the 18-bit resolution then provides sub-microvolt effective resolution across the sensor span.
