AH855

The AH855 is designed as one kind of fully buffered hybrid pre/post PAL filter device that can be employed in either pre A/D or post D/A applications with user selection of the passband shape thereby simplifying the system inventory and ordering procedure.

The absolute maximum ratings of the AH855 can be summarized as:(1)Filter Shape: Lowpass;(2)Passband Shape - user selectable (pin2): Flat or Sinx/x;(3)Sampling Frequency: 27 MHz;(4)End Of Passband: 5.75 MHz;(5)Passband Amplitude Ripple: 0.25 dB max;(6)Start Of Stopband: 21.5 MHz;(7)Group Delay Ripple to 5.75 MHz: Flat is 6 ns max and Sinx/x is 10 ns max;(8)Delay Time at 200 kHz: Flat is 28 ns +/- 2 ns Sinx/x is 25 ns +/- 2 ns;(9)Typical Current: 30 mA (15 mA per rail at +/- 5 v);(10)Input Impedance: 2 M typical;(11)Aqueous Washable: Yes.
