LM567C: Caluculation of Largest Detection Bandwidth

Part Number: LM567C

Hi team,

How do we understand the largest detection bandwidth?

10[% of fo] means if fo=400Hz, 400Hz*10%=40Hz and the bandwidth becomes from 380Hz to 420Hz. Is this understanding correct?

Best regards,

Shunsuke Yamamoto

    Hi Yamamoto-san,

    The chip is designed to provide a saturated transistor switch to ground when an input signal is present within the passband. Detection bandwidth determines this passband. 

    Right, the bandwidth is +/-5% in your example.
