The MAX1003 is a dual, 6-bit analog-to-digital converter (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) analog signals into two 6-bit, offset-binary-coded digital outputs at sampling rates up to 90Msps. The ability to directly interface with baseband I and Q signals makes the MAX1003 ideal for use in direct-broadcast satellite, VSAT, and QAM16 demodulation applications. The MAX1003 input amplifiers feature true differential inputs, a -0.5dB analog bandwidth of 55MHz, and user-programmable input full-scale ranges of 125mVp-p, 250mVp-p, or 500mVp-p. 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 effective number of bits (ENOB) with a 20MHz analog input signal, or 5.7 ENOB with a 50MHz signal. The MAX1003 operates with +5V analog and +3.3V digital supplies for easy interfacing to +3.3V-logic-compatible digital signal processors and microprocessors. It comes in a 36-pin SSOP package.
