NOTES:
5. The filter gain outside of the passband is measured with respect to the gain at 1020 Hz. The analog input test signal is a sine wave
with 0 dBr = 4 VI(PP) differential as the reference level for ADC analog input signal.
6. When the high-pass filter is bypassed, the passband is 0 Hz to 3 kHz. When the high-pass filter is inserted, the passband is 300 Hz
to 3 kHz.
7. When the high-pass filter is bypassed, the passband is 0 kHz to 6 kHz. When the high-pass filter is inserted, the passband is 600 Hz
to 6 kHz.

NOTES:
5. The filter gain outside of the passband is measured with respect to the gain at 1020 Hz. The analog input test signal is a sine wave
with 0 dBr = 4 VI(PP) differential as the reference level for ADC analog input signal.
8. The test condition is a 1020-Hz input signal with an 8-kHz conversion rate. Input and output common mode is 1.5 V.
