Low Power: 0.75mW/channel  
Input-Referred Noise: 4mVPP (150Hz BW, G = 6)  
Input Bias Current: 200pA  
The ADS1294/6/8 have a flexible input multiplexer  
per channel that can be independently connected to  
the internally-generated signals for test, temperature,  
and lead-off detection. Additionally, any configuration  
of input channels can be selected for derivation of the  
right leg drive (RLD) output signal. The ADS1294/6/8  
operate at data rates as high as 32kSPS, thereby  
allowing the implementation of software pace  
detection. Lead-off detection can be implemented  
internal to the device, either with a pull-up/pull-down  
resistor or an excitation current sink/source. Three  
integrated amplifiers generate the Wilson Central  
Terminal (WCT) and the Goldberger Central  
Terminals (GCT) required for a standard 12-lead  
ECG.  
Data Rate: 250SPS to 32kSPS  
CMRR: –115dB

DESCRIPTION  
The ADS1294/6/8 are a family of multichannel,  
simultaneous sampling, 24-bit, delta-sigma (ΔΣ)  
analog-to-digital converters (ADCs) with a built-in  
programmable gain amplifier (PGA), internal  
reference, and an onboard oscillator. The  
ADS1294/6/8 incorporate all of the features that are  
commonly required in medical electrocardiogram  
(ECG) and electroencephalogram (EEG) applications.
