What are the key features of ADS1293CISQX?
- Integrated multi-channel biopotential analog front end with PGA, ADC, and lead-off detection reduces external component count for ECG and EEG acquisition systems
- Wide supply voltage range of 2.7 V to 5.5 V enables operation from single Li-ion cell (3.0–4.2 V) in portable and wearable medical devices
- Low-power architecture minimizes battery drain in continuous patient monitoring wearables requiring 24/7 biopotential signal recording
- 28-pin QFN (very thin chip carrier) package with exposed thermal pad enables compact, low-profile PCB designs in miniaturized medical sensor modules
What is ADS1293CISQX used for?
ADS1293CISQX is engineered for medical biopotential acquisition applications including portable ECG monitors, Holter recorders, and ambulatory EEG systems where low noise, low power, and integrated signal conditioning are critical for accurate physiological signal capture. Its integrated PGA and multi-channel ADC architecture supports simultaneous acquisition of 3-lead or multi-lead ECG signals with high common-mode rejection, making it ideal for clinical patient monitoring and remote cardiac telemetry devices. Wearable fitness trackers, impedance cardiography systems, and neural signal recording instruments also leverage its 2.7 V minimum supply and compact 28-pin QFN footprint for miniaturized, battery-efficient health sensing designs.

Frequently Asked Questions
What supply voltage does ADS1293CISQX require, and how does this enable wearable medical device designs?
ADS1293CISQX operates from 2.7 V to 5.5 V with 3.6 V nominal, directly compatible with a single Li-ion cell (3.0–4.2 V) or two AA batteries (2.7–3.2 V), enabling fully standalone wearable ECG and EEG monitors without a boost converter or voltage regulator stage.
What biopotential signals can ADS1293CISQX acquire, and what signal conditioning does it integrate on-chip?
ADS1293CISQX acquires ECG, EEG, and EMG biopotential signals with amplitudes from 0.1 mV to 10 mV, integrating programmable gain amplifiers (PGA), delta-sigma ADC channels, lead-off detection, and right-leg drive support in a single 28-pin IC, eliminating 5–8 discrete analog components.
How does ADS1293CISQX handle electrode contact quality monitoring in ECG applications?
ADS1293CISQX includes integrated lead-off detection circuitry that monitors DC or AC impedance between ECG electrodes and skin, flagging poor contact when impedance exceeds a programmable threshold (typically above 1 kΩ to 100 kΩ), ensuring data quality alerts in ambulatory cardiac monitoring systems.
What end-of-life status does ADS1293CISQX carry, and what should medical device engineers plan for ongoing production?
ADS1293CISQX has YTEOL of 0, meaning it is at or near end-of-life. Medical device engineers should initiate last-time-buy orders to stock 18–36 months of supply, qualify a pin-compatible replacement AFE IC, and notify regulatory bodies of any component changes requiring re-certification before production transitions.
