The ADC converts analog signals into binary-coded digital outputs at sampling rates up to 90Msps. The ability to directly interface with baseband signals makes the MAX1011 ideal for use in a wide range of communications and instrumentation applications. The MAX1011’s input amplifier features a true differential input, a -0.5dB analog bandwidth of 55MHz, and a userprogrammable input full-scale range of 125mVp-p, 250mVp-p, or 500mVp-p. With an AC-coupled signal, input offset is typically less than 1/4LSB. Dynamic performance is 5.85 effective number of bits (ENOB) with a 20MHz analog input signal, or 5.7 ENOB with a 50MHz signal.
