19-4802; Rev 2; 9/04

10-Bit, 105Msps, Single 3.3V, Low-Power

ADC with Internal Reference

General Description

Features

The MAX1449 3.3V, 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 dif-

ferential signal path. The ADC is optimized for low-

power, high-dynamic performance in imaging and digital

communications applications. The converter operates

from a single 2.7V to 3.6V supply, consuming only

186mW while delivering a 58.5dB (typ) signal-to-noise

ratio (SNR) at a 20MHz input frequency. The fully differ-

ential input stage has a -3dB 400MHz bandwidth and

may be operated with single-ended inputs. In addition to

low operating power, the MAX1449 features a 5µA

power-down mode for idle periods.

♦ Single 3.3V Operation

♦ Excellent Dynamic Performance

58.5dB SNR at f = 20MHz

72dBc SFDR at f = 20MHz

♦ Low Power

62mA (Normal Operation)

5µA (Shutdown Mode)

♦ Fully Differential Analog Input

♦ Wide 2Vp-p Differential Input Voltage Range

♦ 400MHz -3dB Input Bandwidth

♦ On-Chip 2.048V Precision Bandgap Reference

♦ CMOS-Compatible Three-State Outputs

♦ 32-Pin TQFP Package

An internal 2.048V precision bandgap reference is

used to set the ADC’s full-scale range. A flexible refer-

ence structure allow’s the user to supply a buffered,

direct, or externally derived reference for applications

requiring increased accuracy or a different input volt-

age range.

♦ Evaluation Kit Available (MAX1448 EV Kit)

Ordering Information

Lower speed, pin-compatible versions of the MAX1449

are also available. Refer to the MAX1444 data sheet for

a 40Msps version, the MAX1446 data sheet for a

60Msps version, and the MAX1448 data sheet for 80Msps.

The MAX1449 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.
