Octal, 12-Bit, 64Msps, 1.8V ADC

with Serial LVDS Outputs

MAX1438B

General Description

Features

The MAX1438B octal, 12-bit analog-to-digital converter

(ADC) features fully differential inputs, a pipelined

architecture, and digital error correction incorporating a

fully differential signal path. This ADC is optimized for

low-power and high-dynamic performance in medical

imaging instrumentation and digital communications

applications. The MAX1438B operates from a 1.8V sin-

gle supply and consumes only 913mW (114mW per

channel) while delivering a 69.9dB (typ) signal-to-noise

ratio (SNR) at a 5.3MHz input frequency. In addition to

low operating power, the MAX1438B features a low-

power standby mode for idle periods.

♦ Excellent Dynamic Performance

69.9dB SNR at 5.3MHz

94dBc SFDR at 5.3MHz

♦ Ultra-Low Power

114mW per Channel (Normal Operation)

♦ Serial LVDS Outputs

♦ Pin-Selectable LVDS/SLVS (Scalable Low-Voltage

Signal) Mode

♦ LVDS Outputs Support Up to 30in FR4 Backplane

An internal 1.24V precision bandgap reference sets the

full-scale range of the ADC. A flexible reference struc-

ture allows the use of an external reference for applica-

tions requiring increased accuracy or a different input

voltage range. The reference architecture is optimized

for low noise.

Connections

♦ Test Mode for Digital Signal Integrity

♦ Fully Differential Analog Inputs

♦ Wide Differential Input Voltage Range (1.4V

)

P-P

A single-ended clock controls the data-conversion

process. An internal duty-cycle equalizer compensates

for wide variations in clock duty cycle. An on-chip

phase-locked loop (PLL) generates the high-speed ser-

ial low-voltage differential signal (LVDS) clock.

♦ On-Chip 1.24V Precision Bandgap Reference

♦ Clock Duty-Cycle Equalizer

♦ Compact, 68-Pin Thin QFN Package with Exposed

Pad

The MAX1438B has self-aligned serial LVDS outputs for

data, clock, and frame-alignment signals. The output

data is presented in two’s-complement format.

♦ Evaluation Kit Available (Order MAX1437BEVKIT)

The MAX1438B offers a maximum sample rate of

64Msps. This device is available in a small, 10mm x

10mm x 0.8mm, 68-pin thin QFN package with exposed

pad and is specified for the extended industrial (-40°C

to +85°C) temperature range.
