_______________Detailed Description
Converter Operation
The MAX1002 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 MAX1002’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 (Ps) with +5V CMOS-
compatible logic interfaces. Figure 1 shows the
MAX1002 in a typical application.
Programmable Input Amplifiers
The MAX1002 has in-phase (I) and quadrature (Q) pro-
grammable-gain input amplifiers with a 55MHz
-0.5dB bandwidth and true differential inputs. To maxi-
mize performance in high-speed systems, each amplifier
has less than 5pF of input capacitance. The input ampli-
fier gain is programmed via the GAIN pin to provide
three possible input full-scale ranges (FSR) (Table 1).
