It samples at 400k samples per second and presents data over a parallel interface, making it a straightforward drop-in for microprocessor-based data acquisition systems that need a clean 12-bit path without serial protocol overhead. ## Input flexibility and supply rails The ADC accepts either pseudo-differential or single-ended inputs, configurable across 4 or 8 channels via the internal mux. The analog supply is fixed at 5 V, while the digital supply runs from 2.7 V to 5.5 V. ## Lifecycle and compliance The MAX1290ACEI+ is listed as Active on Maxim's product status and is ROHS3 compliant.","metaTitle":"MAX1290ACEI+ 12-Bit SAR ADC, 400k SPS, 28-QSOP","metaDescription":"Maxim MAX1290ACEI+ 12-bit SAR ADC, 400k sampling rate, parallel interface, 5V analog/2.7-5.5V digital supply.
