The Microchip MCP3562-E/ST is a 24-bit sigma-delta ADC in a 20-TSSOP package, sampling at 153.6 kS/s over an SPI interface. Two internal A/D converters let you digitise differential or single-ended signals from up to four inputs.
153.6 kS/s — sizing the throughput for your sensor loop
At 153.6 kS/s the MCP3562 covers most industrial sensor acquisition — pressure transducers, load cells, thermocouple arrays — without oversampling overhead. The sigma-delta architecture inherently pushes quantization noise out of the passband, so you get clean 24-bit data at moderate rates. If your application needs faster conversion (above 200 kS/s), look at SAR alternatives; for sub-100 S/s precision, this part gives you headroom to decimate and average for extra noise reduction.
Differential inputs and on-chip PGA — why the BOM shrinks
The PGA lets you amplify small sensor signals (millivolt-level bridge outputs) before conversion, eliminating an external instrumentation amplifier. The internal temperature sensor can monitor the PCB ambient for software compensation of offset drift. For single-ended signals, you still get the full 24-bit dynamic range, but differential mode cancels common-mode noise from long cable runs — a real advantage in motor-drive or industrial environments.
Temperature range and supply rails — fit for industrial and automotive
The digital supply can also run at 1.8 V for low-power controller interfaces.
