Frequently Asked Questions
Does the LTC2400 require external calibration or setup?
No, the LTC2400 performs offset/full-scale calibration transparently to the user, eliminating the need for external calibration.
Can the LTC2400 handle line frequency noise (50Hz/60Hz)?
Yes, it rejects 50Hz/60Hz line frequency noise by 120dB through its integrated anti-aliasing filter.
Is a Programmable Gain Amplifier (PGA) required for use?
No, the LTC2400 uses a third-order modulator and does not require an external PGA.
What are suitable low-noise applications for this ADC?
It is ideal for DC voltage/current measurements, gas analysis, weigh scales, and measuring high DC accuracy signals.
