MAX1003CAX+

The MAX1003CAX+ is a low power, 90Msps, dual 6bit analogue to digital converter in 36 pin SSOP package. It is a dual, 6bit ADC that combines high speed, low power operation with a user-selectable input range, an internal reference and a clock oscillator. The dual parallel ADCs are designed to convert in-phase (I) and quadrature (Q) analogue signals into two 6bit, offset-binary-coded digital outputs at sampling rates up to 90Msps. The ability to directly interface with baseband I and Q signals makes it ideal for use in direct-broadcast satellite, VSAT and QAM16 demodulation applications. It features true differential inputs, a -0.5dB analogue bandwidth of 55MHz and user programmable input full-scale ranges of 125mVpp, 250mVpp or 500mVpp. With an AC-coupled input signal, matching performance between input channels is typically better than 0.1dB gain, 1/4LSB offset and 0.5° phase. Dynamic performance is 5.85 ENOB with a 20MHz analogue input signal or 5.7 ENOB with a 50MHz signal.
