S459D –JANUARY 2010–REVISED MAY 2010
Low-Power, 8-Channel, 24-Bit Analog Front-End for Biopotential Measurements
Check for Samples: ADS1294, ADS1296, ADS1298
1FEATURES With its high levels of integration and exceptional
performance, the ADS1294/6/8 family enables the
23• Eight Low-Noise PGAs and
creation of scalable medical instrumentation systems
Eight High-Resolution ADCs (ADS1298)
at significantly reduced size, power, and overall cost.
• Low Power:
The ADS1294/6/8 have a flexible input multiplexer
• Input-Referred Noise: 4mVPP (150Hz BW, G = 6) per channel that can be independently connected to
• Input Bias Current: 200pA the internally-generated signals for test, temperature,
• Data Rate: 250SPS to 32kSPS and lead-off detection. Additionally, any configuration
of input channels can be selected for derivation of the
• CMRR: –115dB
right leg drive (RLD) output signal. The ADS1294/6/8
• Programmable Gain: 1, 2, 3, 4, 6, 8, or 12 operate at data rates as high as 32kSPS, thereby
• Supplies: Unipolar or Bipolar allowing the implementation of software pace
– Analog: to detection. Lead-off detection can be implemented
internal to the device, either with a pull-up/pull-down
– Digital: to resistor or an excitation current sink/source. Three
• Built-In Right Leg Drive Amplifier, Lead-Off integrated amplifiers generate the Wilson Central
Detection, WCT, Test Signals Terminal (WCT) and the Goldberger Central
• Pace Detection Terminals (GCT) required for a standard 12-lead
ECG.
• Digital Pace Detection Capability
Multiple ADS1294/6/8 devices can be cascaded in
• Built-In Oscillator and Reference
high channel count systems in a daisy-chain
• Flexible Power-Down, Standby Mode configuration.
• SPI™-Compatible Serial Interface Package options include a tiny 8mm × 8mm, 64-ball
• Operating Temperature Range: 0°C to +70°C BGA and a TQFP-64. Both packages are specified
