Overview
The MAX1263BCEG+ is a low-power, 12-bit analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This device features a successive-approximation ADC, automatic power-down, and a fast wake-up time of 2µs. It operates with a single +3V analog supply and includes an on-chip clock and a +2.5V internal reference. The MAX1263BCEG+ is designed for high-speed applications with a byte-wide parallel interface and is suitable for battery-powered and data-acquisition systems due to its low power consumption and small package size.
