OVERVIEW
GebraBit ADS1192 is 4 lead, 2 simultaneous channel sampling, 16 Bit ECG sensor Module.
GebraBit ADS1192 needs 2 voltages for both analog and digital supply of ADS1192. As a result, 2 jumper selector is considered to user select desired supply voltage between 3V3, and 5V.
GebraBit ADS1192 offers 2 choices for ADS1192 clock source ; one is ADS1192 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 ADS1192 module benefits from 2 channels of ADS1192 sensor due to considered TYPE-C female socket. This means a custom-built 5-lead ECG cable is provided to cover this requirement.Ofcourse you need just 4 lead out of 5!
Another important issue of GebraBit ADS1192 is that this module is Pin Compatible with GEBRABUS , and users can access all important I/O of ADS1192 . For reading data and configuring the sensor, an SPI interface is required.
This Module carries ADS1192, a family of multichannel,simultaneous sampling, 16-bit, delta-sigma (ΔΣ)analog-to-digital converters (ADCs) with a built-inprogrammable gain amplifier (PGA), internal reference, and an onboard oscillator.The ADS1191/2 operate at data rates as high as 8kSPS.Lead-off detection can be implemented internal to the device,using the device internal excitation current sink/source.The ADS1191/2 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.
