Frequently Asked Questions

What is the effective resolution and input range of MCP3422A0-E/MC at its slowest sample rate?

At 3.75 SPS, the MCP3422A0-E/MC delivers its full 18-bit resolution over a ±2.048 V differential input range, giving designers maximum dynamic range of approximately 131,072 codes per volt. This makes it ideal for precision weigh-scale and low-drift sensor readout applications.

How many MCP3422A0-E/MC devices can share a single I2C bus in a multi-channel data acquisition design?

The MCP3422A0-E/MC has a factory-programmed I2C address with A0 variant code, and Microchip offers address variants A0 through A7, allowing up to 8 devices on a single I2C bus. Each device provides 2 differential channels, enabling up to 16 differential inputs with 18-bit resolution.

For a temperature-measurement design, how does MCP3422A0-E/MC's integrated PGA benefit low-output thermocouple sensors?

The MCP3422A0-E/MC integrates a programmable gain amplifier with gains of 1×, 2×, 4×, and 8×, directly amplifying small thermocouple signals typically in the microvolt-to-millivolt range without an external op-amp stage. At 8× gain the effective input range narrows to ±256 mV, matching common thermocouple output spans.

What PCB footprint and package constraints apply when using MCP3422A0-E/MC in a compact board design?

The MCP3422A0-E/MC is housed in a DFN-8 package (2 mm × 3 mm body) with an exposed thermal pad, providing a small footprint suitable for space-constrained portable instruments. The 0.5 mm pitch requires standard fine-pitch SMT assembly and reflow soldering practices for reliable connections.
