General Description
The MAX1446 10-bit, 3V analog-to-digital converter
(ADC) features a fully differential input, a pipelined 10-
stage ADC architecture with digital error correction and
wideband track and hold (T/H) incorporating a fully dif-
ferential signal path. This ADC is optimized for low-
power, high dynamic performance applications in
imaging and digital communications. The MAX1446
operates from a single 2.7V to 3.6V supply, consuming
only 90mW while delivering a 59.5dB signal-to-noise
ratio (SNR) at a 20MHz input frequency. The fully differ-
ential input stage has a 400MHz, -3dB bandwidth and
may be operated with single-ended inputs. In addition
to low operating power, the MAX1446 features a 5A
power-down mode for idle periods.
An internal 2.048V precision bandgap reference is used
to set the ADC full-scale range. A flexible reference
structure allows the user to supply a buffered, direct or
externally derived reference for applications requiring
increased accuracy or a different input voltage range.
Lower and higher speed, pin-compatible versions of
the MAX1446 are also available. Refer to the MAX1444
data sheet for a 40Msps version, the MAX1448 data
sheet for an 80Msps version, and the MAX1449 data
sheet for a 105Msps version.
The MAX1446 has parallel, offset binary, three-state
outputs that can be operated from 1.7V to 3.3V to allow
flexible interfacing. The device is available in a 5mm x
5mm, 32-pin TQFP package and is specified over the
extended industrial (-40°C to +85°C) and automotive
(-40°C to +105°C) temperature ranges.
