The filter type is selected using the two filter se- lect pins, TYPE and FSEL, FSEL is a CMOS level pin that selects lowpass or bandpass (lowpass = 0, bandpass = 1). TYPE Is a tertiary control pin that selects the filter response. State 0 is VSS, state 1 is GND and state 2 is VDD.

The frequency control pin F0 is a CMOS level pin where HIGH is clock to corner of 12.5 to 1 (25 to 1 for Bessel) and LOW is clock to corner of 6.25 to 1 (12.5 to 1 for Bessel). The sample rate ratio is twice the clock to corner ratio (double sampling). FSEL IN OUT GND TYPE VSS CLK 5 VDD TYPE S1 S2 OUT CLK FSEL G IN4 VDD IN3 PD IN2 VSS IN1 F0 GND
