We am currently looking around how to improve a design to read lower voltages (amplify) from one of our sensors with a delta sigma ADC.
We are using the 24-bit ADS1219 with all four channels connected. One of these channels needs to read small voltage signals from a SiPM. We can, with the current gain of 4.
However we would like to amplify this signal to at least 20x (25dB, gain). Voltage range: 0V-5V (supply can be -5V to +5V) and preferably low noise.
Can someone help me in the right direction finding a suitable OpAmp and/or reference design for this? Any other ADC recommendation with integrated Gain also welcome!
Thanks in advance!
(actually this question might be more of a Amplifier question)
