Low-Power, 90Msps, Dual 6-Bit ADC
_______________General Description
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.

_______________Detailed Description
Converter Operation
The MAX1003 contains two 6-bit analog-to-digital con-
verters (ADCs), a buffered voltage reference, and oscil-
lator circuitry. The ADCs use a flash conversion
technique to convert an analog input signal into a 6-bit
parallel digital output code. The MAX1003’s unique
design includes 63 fully differential comparators and a
proprietary encoding scheme that ensures no more
than 1LSB dynamic encoding error. The control logic
interfaces easily to most digital signal processors
(DSPs) and microprocessors (µPs) with +3.3V CMOS-
compatible logic interfaces. Figure 1 shows the
MAX1003 in a typical application.
Programmable Input Amplifiers
The MAX1003 has two (I and Q) programmable-gain
input amplifiers with a -0.5dB bandwidth of 55MHz and
true differential inputs. To maximize performance in
high-speed systems, each amplifier has less than 5pF
of input capacitance. The input amplifier gain is pro-
grammed, via the GAIN pin, to provide three possible
input full-scale ranges (FSRs) as shown in Table 1.
