10-bit SAR ADC with 1.8 Msps — what the specs mean for your signal chain
The MAX1072ETC+ is a 10-bit successive-approximation-register (SAR) ADC from Analog Devices, sampling at 1.8 Msps (megasamples per second) over an SPI digital interface. The differential input architecture rejects common-mode noise picked up on long sensor leads or ground offsets — a real advantage when the signal source sits meters from the ADC on a factory floor or test head.
Supply rails and input range — what the board needs to deliver
The reference is external, so the full-scale input range tracks the reference voltage you supply; a precision reference like the ADR4525 keeps the measurement stable across temperature. The single differential input samples at a 1:1 S/H-to-ADC ratio — one conversion per trigger. For multiplexed applications you need an external analog mux ahead of the ADC; the 1.8 Msps throughput still leaves headroom to scan several channels sequentially.
Package, temperature grade, and board integration
Housed in a 12-lead WQFN with exposed pad, the supplier device package is 12-TQFN measuring 4x4 mm. Surface-mount assembly with the standard lead-free reflow profile for QFN packages applies. The industrial temperature grade means the ADC's offset and gain drift stay within the datasheet limits across the full range — no derating needed at 85°C ambient.
