Frequently Asked Questions
How does the differential input configuration of MCP3304-CI/P reduce noise in industrial sensor measurements?
The MCP3304-CI/P provides 4 differential input pairs that reject common-mode noise injected equally onto both signal lines, which is critical in industrial environments where long cable runs pick up 50 Hz or 60 Hz interference. Each differential pair measures signals within the ±5 V analog input range, allowing direct connection to bridge sensor outputs with typical common-mode noise rejection exceeding 60 dB.
At what SPI clock rate can MCP3304-CI/P complete a conversion, and how many channels can be sampled per second?
The MCP3304-CI/P achieves a maximum conversion time of 6.19 µs, which corresponds to a throughput rate of approximately 100,000 samples per second at a 1.6 MHz SPI clock. When multiplexing all 8 single-ended channels, the effective per-channel sample rate is about 12,500 samples per second per channel, sufficient for slow-moving process variables such as temperature or pressure.
Can MCP3304-CI/P measure bridge sensor outputs from a Wheatstone bridge powered at 5 V?
Yes, the MCP3304-CI/P accepts differential inputs within the ±5 V analog input range, which covers the millivolt-level differential output of a 5 V-powered Wheatstone bridge. The 13-bit resolution provides approximately 1.2 mV per LSB with a 5 V reference, enabling detection of small bridge imbalances caused by strain, pressure, or force without preamplification in low-noise laboratory applications.
What are the packaging and lead time considerations for MCP3304-CI/P in production builds?
The MCP3304-CI/P is supplied in a PDIP-16 through-hole package with a factory lead time of approximately 6 weeks. For higher-volume surface-mount assembly, the SOIC-16 package variant of the MCP3304 family may be more appropriate for tape-and-reel SMT placement. The part is RoHS-compliant and lead-free, meeting JESD-609 code e3 environmental compliance standards.
