Quad/Octal, Simultaneous Sampling, 24-Bit Analog-to-Digital Converters

FEATURES  
DESCRIPTION  
234  
•
Simultaneously Measure Four/Eight Channels  
•
•
Up to 128kSPS Data Rate  
Based on the single-channel ADS1271, the ADS1274  
(quad) and ADS1278 (octal) are 24-bit, delta-sigma  
(ΔΣ) analog-to-digital converters (ADCs) with data  
rates up to 128k samples per second (SPS), allowing  
simultaneous sampling of four or eight channels. The  
devices are offered in identical packages, permitting  
drop-in expandability.  
AC Performance:  
62kHz Bandwidth  
111dB SNR (High-Resolution Mode)  
–108dB THD  
•
•
DC Accuracy:  
0.8μV/°C Offset Drift  
1.3ppm/°C Gain Drift  
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 ADS1274  
and ADS1278 combine these types of converters,  
allowing high-precision industrial measurement with  
excellent dc and ac specifications.  
Selectable Operating Modes:  
High-Speed: 128kSPS, 106dB SNR  
High-Resolution: 52kSPS, 111dB SNR  
Low-Power: 52kSPS, 31mW/ch  
Low-Speed: 10kSPS, 7mW/ch

Linear Phase Digital Filter  
SPI™ or Frame-Sync Serial Interface  
Low Sampling Aperture Error  
Modulator Output Option (digital filter bypass)  
Analog Supply: 5V  
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 0.005dB of ripple.  
Digital Core: 1.8V  
I/O Supply: 1.8V to 3.3V  
APPLICATIONS  
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 devices are fully specified over the extended  
industrial range (–40°C to +105°C) and are available  
in an HTQFP-64 PowerPAD™ package.
