It samples at 500k samples per second (SPS) over a single-ended input, with data transferred via SPI. The 500k SPS throughput means this ADC completes one conversion in 2 µs — fast enough to digitize a 250 kHz analog signal under Nyquist, making it suitable for real-time sensor feedback loops in motor control or battery monitoring where the ECU polls a channel every few microseconds. The -40°C to +125°C operating range covers under-hood and transmission-bay ambient conditions without derating. ## Supply rails and analog-digital split The reference is external (not on-chip), so the full-scale range and noise floor are set by the reference voltage you supply — choose a low-drift reference like the MCP1501 to maintain 12-bit accuracy across temperature. ## Package, footprint, and sourcing posture The tube packaging (50 units per tube) suits prototype and low-volume production runs.","metaTitle":"MCP33141-05-E/MS ADC, 12-bit SAR, 500k SPS, AEC-Q100","metaDescription":"Microchip MCP33141-05-E/MS, 12-bit SAR ADC, 500k SPS, single-ended, SPI, -40°C to +125°C, AEC-Q100 qualified.
