MAX1003CAX+T

Analog To Digital Converters (ADC) Overview

The MAX1003CAX+T is a dual, 6-bit analog-to-digital converter (ADC) designed for high-speed, low-power operation. It features two parallel ADCs capable of converting in-phase and quadrature signals at sampling rates up to 90Msps. The device includes true differential input amplifiers with a -0.5dB bandwidth of 55MHz and user-selectable full-scale ranges of 125mVp-p, 250mVp-p, or 500mVp-p. It operates on +5V analog and +3.3V digital supplies, offering flexible CMOS-compatible digital outputs. Dynamic performance reaches 5.85 ENOB with a 20MHz input signal. The component is housed in a 36-pin SSOP package.
