• Input Bias Current: 200pA multiplexer per channel that can be independently
• Data Rate: 250SPS to 32kSPS connected to the internally-generated signals for test,
temperature, and lead-off detection. Additionally, any
• CMRR: –115dB configuration of input channels can be selected for
• Programmable Gain: 1, 2, 3, 4, 6, 8, or 12 derivation of the right leg drive (RLD) output signal.
• Supports AAMI EC11, EC13, IEC60601-1, The ADS1294/6/8/4R/6R/8R operate at data rates as
IEC60601-2-27, and IEC60601-2-51 Standards high as 32kSPS, thereby allowing the implementation
of software PACE detection. Lead-off detection can
• Unipolar or Bipolar Supplies: be implemented internal to the device, either with a
AVDD = 2.7V to 5.25V, DVDD = 1.65V to 3.6V pull-up/pull-down resistor or an excitation current
• Built-In Right Leg Drive Amplifier, Lead-Off sink/source. Three integrated amplifiers generate the
Detection, WCT, PACE Detection, Test Signals Wilson Central Terminal (WCT) and the Goldberger
• Integrated Respiration Impedance Central Terminals (GCT) required for a standard 12-lead ECG. The ADS1294R/6R/8R versions
Measurement (ADS1294R/6R/8R only) include a fully-integrated, respiration impedance
• Digital PACE Detection Capability measurement function.
• Built-In Oscillator and Reference Multiple ADS1294/6/8/4R/6R/8R devices can be
• Flexible Power-Down, Standby Modes cascaded in high channel count systems in a
• SPI™-Compatible Serial Interface daisy-chain configuration.
• Operating Temperature Range: Package options include a tiny 8mm × 8mm, 64-ball
–40°C to +85°C BGA and a TQFP-64. The ADS1294/6/8 BGA version
is specified over the commercial temperature range of
APPLICATIONS 0°C to +70°C. The ADS1294R/6R/8R BGA and
ADS1294/6/8 TQFP versions are specified over the
• Medical Instrumentation (ECG, EMG and EEG): industrial temperature range of –40°C to +85°C.
Patient monitoring; Holter, event, stress, and
vital signs including ECG, AED, telemedicine

(EAP), Sleep study monitor
• High-Precision, Simultaneous, Multichannel
Signal Acquisition


The ADS1294/6/8/4R/6R/8R are a family of
multichannel, simultaneous sampling, 24-bit,
delta-sigma (ΔΣ) analog-to-digital converters (ADCs)
with built-in programmable gain amplifiers (PGAs),
internal reference, and an onboard oscillator. The
ADS1294/6/8/4R/6R/8R incorporate all of the features
that are commonly required in medical
electrocardiogram (ECG) and electroencephalogram
(EEG) applications.
