ANALOG DEVICES ADAS1000-1BCPZ Analog Front End, Electrocardiogram, 5 Ch, 3.15-5.5V, 24 bits, DSP, QSPI, Serial, SPI, LFCSP-EP-56

ADAS1000-1BCPZ is a low-power, five-electrode electrocardiogram (ECG) analogue front end. It measures electro cardiac (ECG) signals, thoracic impedance, pacing artifacts, and lead-on/lead-off status and outputs this information in the form of a data frame supplying either lead/vector or electrode data at programmable data rates. Its low power and small size make it suitable for portable, battery-powered applications. The high performance also makes it suitable for higher-end diagnostic machines. It offers only ECG channels with no respiration or pace features. It is designed to simplify the task of acquiring and ensuring quality ECG signals. It provides a low-power, small data acquisition system for biopotential applications. It is used in applications such as ECG: monitor and diagnostic, bedside patient monitoring, portable telemetry, holter, AED, cardiac defibrillators, ambulatory monitors, pacemaker programmers, patient transport, and stress testing.

• Biopotential signals in; digitized signals out, 5 acquisition (ECG) channels and one driven lead
• Thoracic impedance measurement (internal/external path), low or high speed data output rates
• Scalable noise vs. power control, power-down modes, fast overload recovery
• Serial interface SPI-/QSPI�-/DSP-compatible
• Input bias current is ±1nA typical at (AVDD = 3.3V ±5%)
• Differential nonlinearity error is 5ppm typical at (gain = 0, AVDD = 3.3V ±5%)
• Signal-to-noise ratio is 100dB typical at (-0.5dB FS input signal, AVDD = 3.3V ±5%)
• Analog channel bandwidth is 65KHz typical at (AVDD = 3.3V ±5%, IOVDD = 1.65V to 3.6V)
• Voltage noise is 33?V p-p typical at (0.05Hz to 150Hz (ECG band))
• Operating temperature range from -40°C to +85°C, 56-lead LFCSP-VQ package
