14-Bit, 4-Channel, Software-Programmable,

Multiranging, Simultaneous-Sampling ADC

General Description

Features

The MAX1338 14-bit, analog-to-digital converter (ADC)

offers four simultaneously sampled, fully differential input

channels, with independent track-and-hold (T/H) circuitry

for each channel. The input channels are individually

software programmable for input ranges of ±1ꢀ0, ±ꢁ0,

±±.ꢁ0, and ±1.±ꢁ0. The input channels feature fault tol-

erance to ±1ꢂ0. The internal T/H circuits have a 1ꢃns

aperture delay and 1ꢀꢀps aperture-delay matching.

♦ 150ksps Sample Rate per Channel

♦ All Four Input Channels Simultaneously Sampled

16ns Aperture Delay

100ps Aperture-Delay Matching

♦ Channel-Independent Software-Selectable Input

Range: ±10ꢀV ±5ꢀV ±,ꢁ5ꢀV ±1ꢁ,5ꢀ

♦ ±1ꢂꢀ Fault-ꢃolerant Inputs

A 14-bit parallel bus provides the conversion result with

a maximum per-channel output rate of 1ꢁꢀksps

(ꢃꢀꢀksps for all four channels). The MAX1338 has an

on-board oscillator and ±.ꢁ0 internal reference. An

external clock and/or reference can also be used.

♦ Dynamic Performance at 10kHz Input

SNR: ꢂꢂdB

SINAD: ꢂ6dB

SFDR: 98dBc

The MAX1338 operates from a +ꢁ0 supply for analog

inputs and digital core. The device operates from a +±.ꢂ0

to +ꢁ.±ꢁ0 supply for the digital I/O lines. The MAX1338

features two power-saving modes: standby mode and

shutdown mode. Standby mode allows rapid wake-up

and reduces quiescent current to 4mA (typ), and shut-

down mode reduces sleep current to less than 1ꢀµA (typ).

ꢃHD: -83dBc

♦ DC Performance

INL: ±, LSB

DNL: ±1 LSB

Offset Error: ±± LSB

Gain Error: ±0ꢁ1ꢄ FSR

The MAX1338 is available in an 8mm x 8mm x ꢀ.8mm,

ꢁꢃ-pin, thin QFN package. The device operates over

the extended -4ꢀ°C to +8ꢁ°C temperature range.

♦ 1±-Bit Parallel Interface

♦ Internal Clock and Reference ꢀoltage

♦ +5ꢀ Analog and Digital Supplies

♦ +,ꢁꢂꢀ to +5ꢁ,5ꢀ Digital I/O Supply

♦ 56-Pin ꢃhin QFN Package (8mm x 8mm x 0ꢁ8mm)

Applications
