Overview
The MAX1293BCEG+T from Analog Devices Inc./Maxim Integrated is a low-power, 12-bit analog-to-digital converter (ADC) designed for high-performance and compact applications. This ADC features a successive-approximation conversion technique and an input track/hold (T/H) stage, enabling the conversion of analog input signals to 12-bit digital outputs. It operates with a single +3V analog supply and includes a VLOGIC pin that allows direct interface with digital supplies ranging from +1.8V to +5.5V. The device also includes an on-chip clock and a +2.5V internal reference, along with a high-speed, byte-wide parallel interface.
