CBM24AD98Q | 8-Channel 24-bit ADC With Integrated ECG Front End.pdf | 3.55M
The CBM24AD98Q chip is a low-noise, 24-bit synchronized sampling Δ-Σ analog-to-digital converter (ADC), featuring an integrated programmable gain amplifier (PGA), internal voltage reference, and internal oscillator. The CBM24AD98Q encompasses all common functionalities required for electrocardiogram (ECG) and extracranial electroencephalogram (EEG) applications. With its high level of integration and superior performance, the CBM24AD98Q enables the creation of scalable medical instrumentation systems with significantly reduced size, power consumption, and overall cost.Each channel of the CBM24AD98Q includes a flexible input multiplexer, which can be independently connected to internally generated signals for testing, temperature measurements, and lead-off detection. Furthermore, the chip allows for flexible configuration in generating the right leg drive signal. Integrated within the chip are three amplifiers used to generate the Wilson Central Terminal (WCT) and Goldberger Central Terminal (GCT) required for standard 12-lead ECGs.The CBM24AD98Q supports both low-power and high-precision modes, with data sampling rates ranging from 250 samples per second (SPS) up to 32 kilosamples per second (kSPS). For high-channel count systems, multiple CBM24AD98Q chips can be cascaded in a daisy-chain configuration.The CBM24AD98Q is available in either a TQFP-64 package (10mm10mm) or a QFN-64 package (9mm9mm), with an operating temperature range rated from –40°C to +85°C.
