With high levels of integration • Programmable Gain: 1, 2, 3, 4, 6, 8, or 12 and exceptional performance, the ADS129x and • Supports systems meeting AAMI EC11, EC13, ADS129xR enables the development of scalable IEC60601-1, IEC60601-2-27, and IEC60601-2-51 medical instrumentation systems at significantly Standards reduced size, power, and overall cost. • Unipolar or Bipolar Supplies: The ADS129x and ADS129xR have a flexible input – AVDD = 2.7 V to 5.25 V multiplexer (mux) per channel that can be – DVDD = 1.65 V to 3.6 V independently connected to the internally-generated signals for test, temperature, and lead-off detection. • Built-In Right Leg Drive Amplifier, Lead-Off Additionally, any configuration of input channels can Detection, Wilson Center Terminal, Pace be selected for derivation of the right leg drive (RLD) Detection, Test Signals output signal. The ADS129x and ADS129xR operate • Integrated Respiration Impedance Measurement at data rates as high as 32 kSPS, thereby allowing the implementation of software pace detection. Lead- • Digital Pace Detection Capability off detection can be implemented internal to the • Built-In Oscillator and Reference device, either with a pullup or pulldown resistor, or an • SPI™-Compatible Serial Interface excitation current sink or source. Three integrated amplifiers generate the Wilson central terminal (WCT) 2 Applications and the Goldberger central terminals (GCT) required for a standard 12-lead ECG. The ADS129xR versions • Medical Instrumentation (ECG, EMG, and EEG): include a fully integrated, respiration impedance Patient Monitoring; Holter, Event, Stress, and Vital measurement function. Multiple ADS129x and Signs Including ECG, AED, Telemedicine ADS129xR devices can be cascaded in high channel Bispectral Index (BIS), Evoked Audio Potential count systems in a daisy-chain configuration. (EAP), Sleep Study Monitor Package options include a tiny 8-mm × 8-mm, 64-ball BGA, and a TQFP-64. The ADS129x BGA Simplified Schematic version is specified over the commercial temperature range of 0°C to 70°C. The ADS129xR BGA and ADS129x TQFP versions are specified over the industrial temperature range of –40°C to +85°C.
