Key Features
- 3-channel simultaneous biopotential acquisition with integrated 24-bit ADC enables high-resolution ECG, EEG, and EMG signal capture in a single device
- Ultra-low power consumption optimized for wearable and portable medical monitoring where battery life is critical
- Integrated programmable gain amplifier (PGA) and lead-off detection on each channel reduces external component count and BOM cost
Applications
ADS1293CISQX/NOPB is purpose-built for clinical and consumer medical devices requiring high-accuracy biopotential measurement. It serves as the analog front end in portable ECG monitors, Holter recorders, and patient monitoring systems where capturing millivolt-level cardiac signals with minimal noise is essential. Its low power profile and small 28-pin QFN footprint also make it suitable for wearable fitness trackers and remote patient monitoring patches.

Frequently Asked Questions
How many input channels does ADS1293CISQX/NOPB support, and what resolution does its ADC provide?
ADS1293CISQX/NOPB supports 3 simultaneous input channels, each connected to an integrated 24-bit ADC. This high resolution allows the device to accurately digitize microvolt-level biopotential signals such as ECG waveforms without requiring additional external amplification stages.
For a wearable ECG patch design, what supply voltage and package does ADS1293CISQX/NOPB require?
ADS1293CISQX/NOPB operates from a 1.8 V to 3.6 V supply, making it well suited for lithium-coin or single-cell Li-ion powered wearables. It comes in a compact 28-pin QFN (4 mm x 4 mm) package that minimizes PCB area in thin wearable form factors.
When should a designer choose ADS1293CISQX/NOPB over a single-channel AFE for a 3-lead ECG application?
For a 3-lead ECG application, ADS1293CISQX/NOPB is the preferred choice because it integrates 3 simultaneous acquisition channels, eliminating the need for 3 separate single-channel AFEs. This reduces PCB area, lowers total BOM cost, and ensures all 3 leads are sampled synchronously, which is critical for accurate cardiac rhythm analysis.
