Notes: 14. Channel Gain is the nominal full-scale 24-bit output code from the CS5376A digital filter for a 5 VPP
differential signal into the CS5374 analog inputs at 1x gain. Value is offset corrected.
15. Absolute gain accuracy tests the matching of 1x gain across multiple CS5374 channels in a system.
16. Relative gain accuracy tests the tracking of 2x, 4x, 8x, 16x, 32x, 64x gain relative to 1x gain on a single
CS5374 channel.
17. Specification is for the parameter over the specified temperature range and is for the CS5374 device
only. It does not include the effects of external components.
18. Offset voltage is tested with the amplifier inputs connected to the internal 800 Ω termination.
19. The offset after calibration specification is measured from the digitally calibrated output codes of the
CS5376A digital filter.
20. Offset calibration is performed in the CS5376A digital filter and includes the full-scale signal range.
