19-1981; Rev 0; 5/01

12-Bit, 60Msps, +3.3V, Low-Power ADC

with Internal Reference

General Description

Features

The MAX1420, +3.3V, 12-bit analog-to-digital converter

(ADC) features a fully-differential input, pipelined, 12-

stage ADC architecture with wideband track-and-hold

(T/H) and digital error correction, incorporating a fully-

differential signal path. The MAX1420 is optimized for

low-power, high dynamic performance applications in

imaging and digital communications. The converter

operates from a single +3.3V supply, and consumes

only 221mW. The fully-differential input stage has a

small signal -3dB bandwidth of 400MHz and may be

operated with single-ended inputs.

ꢀ +3.3V Single Power Supply

ꢀ 67dB SNR at f = 5MHz

ꢀ 66dB SNR at f = 15MHz

ꢀ Internal +2.048V Precision Bandgap Reference

ꢀ Differential, Wideband Input T/H Amplifier

ꢀ Power-Down Modes:

218mW (Reference Shutdown Mode)

10µW (Shutdown Mode)

An internal +2.048V precision bandgap reference sets

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

structure accommodates an internal reference, or

externally applied buffered or unbuffered reference for

applications that require increased accuracy and a dif-

ferent input voltage range.

ꢀ Space-Saving 48-Pin TQFP Package

In addition to low operating power, the MAX1420 fea-

tures two power-down modes: reference power-down

and shutdown mode. In reference power-down, the

internal bandgap reference is deactivated, which

results in a typical 2mA supply current reduction. A full

shutdown mode is available to maximize power savings

during idle periods.

The MAX1420 provides parallel, offset binary, CMOS-

compatible three-state outputs.

The MAX1420 is available in a 7mm 7mm, 48-pin

TQFP package, and is specified over the commercial

(0°C to +70°C) and the extended industrial (-40°C to

+85°C) temperature range.

Pin Configuration

Pin-compatible lower speed versions of the MAX1420

are also available. Please refer to the MAX1421 data

sheet for 40Msps and the MAX1422 data sheet for

20Msps.
