Overview
The MX7576JN, produced by Analog Devices Inc./Maxim Integrated, is a high-speed, microprocessor-compatible, 8-bit analog-to-digital converter (ADC). This component is part of the MX7575/MX7576 series, known for their fast conversion times and low power dissipation. The MX7576JN uses a successive-approximation technique for conversions and features an on-chip track/hold function, allowing it to accurately digitize full-scale signals up to 50kHz. It operates with a +5V supply and a 1.23V external reference, making it easily interfaced with popular 8-bit microprocessors through standard control signals.
