Other Parts Discussed in Thread: ADS1294
In the 8.3.10.2.1 DC Lead-Off mode of the ADS1292 Datasheet, two modes are provided: a) External Pull-Up/Pull-Down Resistors and b) Input Current Source. We now want to choose the a) method, but we don’t know how to turn off the b) Input Current Source.
In the 8.6.1.4 LOFF register configuration in this datasheet, Bit 4 must be set to ‘1’ according to the description. However, the description of this register in devices of the same type, such as the ADS1294, clearly states that bit4 is the option of VLEAD_OFF_EN, 0 = Current source mode lead-off, 1 = pullup or pulldown resistor mode lead-off.
So, what I urgently want to know is, regarding the description in this section of 8.3.10.2.1 DC Lead-Off, is there only the a) External Pull-Up/Pull-Down Resistors option, but no b) Input Current Source option?
