_______________General Desc ription
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 refer-
ence, 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 sig-
nal, or 5.7 ENOB with a 50MHz signal.
The MAX1003 operates with +5V analog and +3.3V digi-
tal supplies for easy interfacing to +3.3V-logic-compati-
ble digital signal processors and microprocessors. It
comes in a 36-pin SSOP package.
