Other Parts Discussed in Thread: ADS1299-4
Hello,
I'm using an ADC1294 to pick up signals from a sodium chloride solution. For signals larger than 10 Milivolt this works without problems.
I would like to measure signals in the microvolt range and use a low-noise signal generator that can generate 20Hz signals with an amplitude of up to 130µV. Which settings do you recommend? I have currently set a gain factor of 12 and a data rate of 250SPS. Do you think a preamplifier is necessary? The measurements are carried out in a shielded chamber.
AVDD = 3.3V and DVDD = 1.8V
Many thanks in advance!
