General Description
The MAX1011 is a 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 ADC converts analog
signals into binary-coded digital outputs at sampling
rates up to 90Msps. The ability to directly interface with
baseband signals makes the MAX1011 ideal for use in
a wide range of communications and instrumentation
applications.
The MAX1011’s input amplifier features a true differential
input, a -0.5dB analog bandwidth of 55MHz, and a user-
programmable input full-scale range of 125mVp-p,
250mVp-p, or 500mVp-p. With an AC-coupled signal,
input offset is typically less than 1/4LSB. Dynamic per-
formance is 5.85 effective number of bits (ENOB) with a
20MHz analog input signal, or 5.7 ENOB with a 50MHz
signal.
The MAX1011 operates with +5V analog and +3.3V digi-
tal supplies for easy interfacing to +3.3V-logic-compatible
digital signal processors and microprocessors. It comes
in a 24-pin QSOP package.
