4 / 14 page  Filter Electrical Characteristics (Continued) The following specifications apply for f CLK ≤ 250 kHz (Note 5) unless otherwise specified. Boldface limits apply for TMIN to T MAX; all other limits TA = TJ = 25˚C. Parameter Conditions Typical Tested Design Unit (Note 10) Limit Limit (Note 11) (Note 12) V + = +2.5V, V− = −2.5V Stopband Attenuation (Min) at 2 fc −25.0 −24.0 −24.0 dB DC Offset Voltage −150 mV Minimum Output Swing RL = 10 kΩ +1.5 +1.0 +1.0 V −2.2 −1.7 −1.7 V Output Short Circuit Source 28 mA Current (Note 8) Sink 0.5 mA Dynamic Range (Note 4) 78 dB Additional Magnitude fclk = 250 kHz Response Test Points (Note 6) −7.57 −7.57 dB (fc = 5 kHz) f = 6000 Hz ±0.47 ±0.47 Magnitude at f = 4500 Hz −1.46 −1.46 dB ±0.12 ±0.12 (fc = 2.5 kHz) f = 3000 Hz Magnitude dB f = 2250 Hz Logic Input-Output Characteristics The following specifications apply for V − = 0V (Note 7) unless otherwise specified. Boldface limits apply for T MIN to TMAX; all other limits T A = TJ = 25˚C.
