  • ADX911/2 is a multi-channel, simultaneous sampling, 16-bit Delta-Sigma (ΔΣ) analog-to-digital converter (ADC) featuring an integrated programmable gain amplifier (PGA), internal reference, and onboard oscillator. The ADX911/2 encompasses all the necessary functions typically required in portable low-power medical electrocardiogram (ECG) applications, as well as in sports and fitness monitoring. Due to its high level of integration and outstanding performance, the ADX911/2 significantly reduces the size, power consumption, and overall cost of scalable medical instrument systems. Each channel of the ADX911/2 is equipped with a flexible input multiplexer, allowing independent connection to internally generated signals for purposes such as testing, temperature monitoring, and lead-off detection. Additionally, any input channel can be configured to capture the right leg drive (RLD) output signal. The ADX911/2 supports a maximum data rate of up to 8kSPS. Lead-off detection is implemented internally through the use of a current excitation source. The device operates within a temperature range of -40°C to 85°C.
