Frequently Asked Questions

What resolution and sample rate does MCP3422A2-E/SN offer, and how do they trade off?

MCP3422A2-E/SN provides 18-bit resolution at 4 SPS, delivering exceptional accuracy at the cost of low throughput. This trade-off suits slow-changing signals such as temperature sensors, load cells, or pH probes where noise rejection matters more than acquisition speed.

What differential input voltage range is supported by the MCP3422A2-E/SN?

The device accepts a differential analog input range of -2.048 V to +2.048 V, making it compatible with common sensor output levels. The ±2.048 V range corresponds to a full-scale LSB of approximately 15.6 µV at 18-bit resolution.

How does MCP3422A2-E/SN compare to lower-resolution alternatives when choosing for a precision industrial scale design?

For precision industrial scales requiring sub-millivolt discrimination, MCP3422A2-E/SN's 18-bit resolution and 0.0035% maximum linearity error make it superior to 12-bit or 16-bit alternatives. Lower-resolution ADCs may suffice for general monitoring, but metrology-grade weigh scales benefit from the higher bit depth.

What is the lead time for MCP3422A2-E/SN and how should buyers plan their procurement?

MCP3422A2-E/SN carries a factory lead time of approximately 8 weeks. Buyers integrating this 18-bit ADC into production designs should build safety stock or place blanket orders to avoid line stoppages caused by supply delays.
