PARAMETER TEST CONDITIONS
MIN TYP MAX MIN TYP MAX UNIT
The test condition is the digital equivalent of a 1020-Hz input signal with an 8-kHz conversion rate.
DAC Line Output (LINEO-, LINEO+)
The test is measured at output of the application schematic low-pass filter. The test is conducted in
Using FIR Filter
