Overview
The MAX153EAP+ is a high-speed, microprocessor (µP)-compatible, 8-bit analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This ADC utilizes a half-flash conversion technique to achieve a conversion time of 660ns and a sampling rate of 1 million samples per second (Msps). It is designed to operate with either single +5V or dual ±5V power supplies and can handle both unipolar and bipolar input signals. The device features a power-down mode that reduces current consumption to a typical value of 1µA, making it suitable for battery-powered and burst-mode data acquisition applications.
