FEATURES  
DESCRIPTION  
The ADS8634 and ADS8638 (ADS8634/8) are 12-bit  
23  
Selectable Input Range:  
±10V, ±5V, ±2.5V, 0V to 10V, or  
0V to 5V  
analog-to-digital converters (ADCs) capable of  
measuring inputs up to ±10V at 1MSPS. Using a  
successive approximation register (SAR) core, these  
ADCs provide a sample-and-hold front-end with no  
latency in conversions. The ADS8634 includes an  
input multiplexer (mux) for measuring up to four  
inputs. The ADS8638 can measure up to eight inputs.  
Up to ±12V with External Reference  
No Latent Conversions Up to 1MSPS  
Outstanding Performance:  
12 Bits No Missing Codes  
INL: ±0.9LSB  
In addition to the input multiplexer, the ADS8634/8  
feature an internal temperature sensor, voltage  
reference, and a digital comparator for setting alarm  
SNR: 71.8dB  
Highly Integrated:  
4- or 8-Channel Input Mux  
Temperature Sensor  
Internal Voltage Reference  
Alarm Thresholds for Each Channel  
thresholds on each input; therefore,  
a minimal  
amount of external components are required. A  
simple SPI-compatible interface provides for  
communication and control. The digital supply  
operates from 5V all the way down to 1.8V for direct  
connection to a wide range of processors and  
controllers.  
Low Power:  
14.45mW at 1MSPS  
5.85mW at 0.1MSPS  
Flexible Power-Down Mode  
Ideal for demanding industrial measurement  
applications, the ADS8634/8 are fully specified over  
the extended industrial temperature range of 40°C  
to +125°C and are available in a small form-factor  
QFN-24 package.
