GebraBit ADS1194 is 5 lead, 4 simultaneous channel sampling, 16 Bit ECG sensor Module.
GebraBit ADS1194 needs 2 voltages for both analog and digital supply of ADS1194. As a result, 2 jumper selector is considered to user select desired supply voltage among 1V8, 3V3, and 5V.
GebraBit ADS1194 offers 2 choices for ADS1194 clock source ; one is ADS1194 Internal oscillator and the other, external, means on board 2.048Mhz crystal oscillator or ‘CLK’ pin. This is achieved by the ‘CLK SEL’ jumper selector. Also ‘EXT CLK’ jumper demonstrates an external clock source, whether the ‘CLK’ pin or 2.048Mhz Onboard crystal oscillator.
GebraBit ADS1194 module benefits from all 4 channels of ADS1194 sensor due to considered TYPE-C female socket. This means a custom-built 5-lead ECG cable is provided to cover this requirement.
Another important issue of GebraBit ADS1194 is that, although this module is Pin Compatible with GEBRABUS , but also two extra pins is added to the top of each right and left module pins for accessing all important I/O of ADS1194. For reading data and configuring the sensor, an SPI interface is required.
This Module carries ADS1194, which is family of multichannel, simultaneous sampling, 16-bit, delta-sigma (ΔΣ) analog-to-digital converters (ADCs) with a built-in programmable gain amplifier (PGA), internal reference, and an onboard oscillator.The ADS1194/6/8 have 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 right leg drive (RLD) output signal. The ADS1194/6/8 operate at data rates as high as 8kSPS, thereby allowing the implementation of software pace detection.Three integrated amplifiers generate the Wilson Center Terminal (WCT) and the Goldberger terminals (GCT) required for a standard 12-lead medical electrocardiogram (ECG).
