DESCRIPTION

Based on the single-channel ADS1271, the ADS1278

(octal) is a 24-bit, delta-sigma (ΔΣ) analog-to-digital

converter (ADC) with data rates up to 128 k samples

per second (SPS), allowing simultaneous sampling of

eight channels.

Selectable Operating Modes:

High-Speed: 128 kSPS, 106 dB SNR

High-Resolution: 52 kSPS, 111 dB SNR

Low-Power: 52 kSPS, 31 mW/ch

Low-Speed: 10 kSPS, 7 mW/ch

Traditionally, industrial delta-sigma ADCs offering

good drift performance use digital filters with large

passband droop. As a result, they have limited signal

bandwidth and are mostly suited for dc

measurements. High-resolution ADCs in audio

applications offer larger usable bandwidths, but the

offset and drift specifications are significantly weaker

than respective industrial counterparts. The ADS1278

combines these types of converters, allowing high-

precision industrial measurement with excellent dc

and ac specifications.

•

Linear Phase Digital Filter

SPI™ or Frame-Sync Serial Interface

Low Sampling Aperture Error

Modulator Output Option (digital filter bypass)

Analog Supply: 5 V

Digital Core: 1.8 V

I/O Supply: 1.8 V to 3.3 V

Currently Available in an 84-Pin HFQ Package

and a KGD Chiptray Option

The

high-order,

chopper-stabilized

modulator

achieves very low drift with low in-band noise. The

onboard decimation filter suppresses modulator and

signal out-of-band noise. These ADCs provide a

usable signal bandwidth up to 90% of the Nyquist

rate with less than 0.005 dB of ripple.

SUPPORTS EXTREME TEMPERATURE

APPLICATIONS

•

Controlled Baseline

One Assembly/Test Site

One Fabrication Site

Four operating modes allow for optimization of speed,

resolution, and power. All operations are controlled

directly by pins; there are no registers to program.

The device is fully specified over the extended

industrial range (–55°C to 210°C) and is available in

an 84-pin HFQ package and a KGD chiptray option.

Available in Extreme (–55°C/210°C)
