Its architecture combines a 2-input multiplexer with a differential or single-ended front end, feeding a sigma-delta modulator and digital filter — the configuration is MUX-ADC, meaning the mux selects the channel before the converter, not a simultaneous-sampling arrangement. Two on-chip A/D converters operate in parallel, though the input multiplexer limits the effective channel count to two differential or single-ended paths. Reference selection is flexible: the converter accepts either an external precision reference or the internal bandgap reference. The S/H:ADC ratio is 0:2, indicating no dedicated sample-and-hold amplifier ahead of the modulator — the sigma-delta loop's oversampling inherently captures the input signal without a front-end track-and-hold. ## Supply range, temperature grade, and package The -40°C to +125°C operating range covers automotive and industrial ambient, though the die temperature sensor's accuracy should be checked against the system's thermal profile at the high end.","metaTitle":"MCP3462R-E/ST Microchip 16-bit Sigma-Delta ADC, 153.6kSPS","metaDescription":"MCP3462R-E/ST 16-bit Sigma-Delta ADC, 153.6kSPS, 2-ch differential/SE, SPI, -40 to 125°C, 20-TSSOP.

Key differences: the MCP3564 offers 4 or 8 input channels (vs 2), includes a programmable gain amplifier (PGA), and comes in a 20-QFN package (tape-and-reel). It is not a pin-compatible drop-in — the package and pinout differ — but for a board spin the higher resolution and PGA may eliminate external signal conditioning."},{"question":"What compliance documentation does Microchip provide?","answer":"Microchip confirms ROHS3 compliance for the MCP3462R-E/ST.
