This matters for multi-phase power monitoring or vibration analysis where the timing skew between channels would alias the measurement. The parallel data interface outputs all eight conversion results on a 16-bit bus — no serial latency, no daisy-chain delay. ## Supply rails and reference — two decisions that set the noise floor The analog supply is a fixed 5 V rail — the ADC's internal SAR core and input sampling network draw from this. The reference can be either external or internal — using the internal reference saves a component but ties the full-scale range to its accuracy; an external reference decouples the ADC's gain drift from the internal bandgap. In a 250 kSPS continuous conversion stream, the power dissipation is dominated by the digital I/O switching, not the analog core. ROHS3 compliant, so it passes the EU RoHS exemption roll-up without a waiver. The tube package (56-WFQFN) is the standard production format; no special handling beyond normal MSL moisture sensitivity for the QFN package.","metaTitle":"MAX11046ETN+ ADC, 16-Bit, 8-Ch, 250kSPS, 56-TQFN","metaDescription":"Analog Devices MAX11046ETN+ 16-bit SAR ADC, 8 simultaneous-sampling channels, 250kSPS per channel.
