General Description
The MAX1448 3V, 10-bit analog-to-digital converter
(ADC) features a fully differential input, a pipelined 10-
stage ADC architecture with wideband track-and-hold
(T/H), and digital error correction incorporating a fully
differential signal path. The ADC is optimized for low-
power, high dynamic performance in imaging and digi-
tal communications applications. The converter
operates from a single 2.7V to 3.6V supply, consuming
only 120mW while delivering a 59dB (typ) signal-to-
noise ratio (SNR) at a 20MHz input frequency. The fully
differential input stage has a -3dB 400MHz bandwidth
and may be operated with single-ended inputs. In addi-
tion to low operating power, the MAX1448 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 refer-
ence structure allows the user to supply a buffered,
direct, or externally derived reference for applications
requiring increased accuracy or a different input volt-
age range.
Lower speed, pin-compatible versions of the MAX1448
are also available. Refer to the MAX1444 data sheet for
a 40Msps version and to the MAX1446 data sheet for a
60Msps version.
The MAX1448 has parallel, offset binary, CMOS-com-
patible three-state outputs that can be operated from
1.7V to 3.6V 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)
temperature range.
