CBM24AD99Q 8-Channel, 24-Bit, Analog-to-Digital Converter for EEG and Biopotential Measurements

The CBM24AD99Q-4, CBM24AD99Q-6, and CBM24AD99Q devices are a family of four-, six-, and eight-channel, lownoise, 24-bit, simultaneous-sampling delta-sigma (ΔΣ) analog-to-digital converters (ADCs) with a built-in programmable gain amplifier (PGA), internal reference, and an onboard oscillator. The CBM24AD99Q-x incorporates all commonly-required features for extracranial electroencephalogram (EEG) and electrocardiography (ECG) applications. With its high levels of integration and exceptional performance, the CBM24AD99Q-x enables the creation of scalable medical instrumentation systems at significantly reduced size, power, and overall cost. The CBM24AD99Q-x has 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 patient bias output signal. Optional SRB pins are available to route a common signal to multiple inputs for a referential montage configuration. The CBM24AD99Q-x operates at data rates from 250 SPS to 16 kSPS. Lead-off detection can be implemented internal to the device using an excitation current sink or source. Multiple CBM24AD99Q-4, CBM24AD99Q-6, or CBM24AD99Q devices can be cascaded in high channel count systems in a daisy-chain configuration.
The CBM24AD99Q-x is offered in a TQFP-64 package specified from –40°C to +85°C.
