Overview
The MAX153EWP 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 technique to achieve a conversion time of 660ns and digitizes at a rate of 1 million samples per second (Msps). It is designed to operate with either single +5V or dual ±5V supplies and can accept both unipolar and bipolar input signals. The device features a POWERDN (power-down) pin that reduces current consumption to a typical value of 1µA, making it highly efficient in applications with burst-mode input signals.
