Octal, 12-Bit, 65Msps, 1.8V ADC

with Serial LVDS Outputs

MAX1438

General Description

Features

The MAX1438 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 MAX1438 operates from a 1.8V single

supply and consumes only 913mW (114mW per chan-

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

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

operating power, the MAX1438 features a power-down

mode for idle periods.

o Excellent Dynamic Performance

69.9dB SNR at 5.3MHz

95dBc SFDR at 5.3MHz

85dB Channel Isolation

o Ultra-Low Power

114mW per Channel (Normal Operation)

o Serial LVDS Outputs

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

Signal) Mode

o LVDS Outputs Support Up to 30 Inches FR-4

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.

Backplane Connections

o Test Mode for Digital Signal Integrity

o Fully Differential Analog Inputs

o Wide Differential Input Voltage Range (1.4V

)

P-P

o On-Chip 1.24V Precision Bandgap Reference

o Clock Duty-Cycle Equalizer

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 PLL

generates the high-speed serial low-voltage differential

signal (LVDS) clock.

o Compact, 100-Pin TQFP Package with Exposed

Pad

o Evaluation Kit Available (Order MAX1438EVKIT)

The MAX1438 has self-aligned serial LVDS outputs for

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

data is presented in two’s complement or binary format.

Ordering Information

The MAX1438 offers a maximum sample rate of

65Msps. See the Pin-Compatible Versions table below

for lower-speed versions. This device is available in a

small, 14mm x 14mm x 1mm, 100-pin TQFP package

with exposed pad and is specified for the extended

industrial (-40°C to +85°C) temperature range.
