4 / 20 page  Op Amp Electrical Characteristics (Continued) Boldface limits apply for T MIN to TMAX; all other limits TA = TJ = 25˚C. Parameter Conditions Typical Tested Design Units (Note 8) Limit Limit (Note 9) (Note 10) V + = +2.5V, V− = −2.5V Input Bias Current 10 pA CMRR (Op-Amp #2 Only) VCM1 = +0.5V, 60 55 dB VCM2 = −0.9V Output Voltage Swing RL = 10 kΩ +1.5 +1.3 +1.1 V −2.2 −1.7 −1.7 Maximum Output Short Source 24 mA Circuit Current (Note 6) Sink 1.0 Slew Rate 6.0 V/µs DC Open Loop Gain 67 dB Gain Bandwidth Product 1.2 MHz Logic Input-Output Electrical Characteristics (Note 5) The following specifications apply for V − = 0V unless otherwise specified. Boldface limits apply for T MIN to T MAX; all other limits TA = TJ = 25˚C.

Note 2: For ±5V supplies the dynamic range is referenced to 2.82 Vrms (4V peak) where the wideband noise over a 20 kHz bandwidth is typically 200 µVrms for the MF6-50 and 250 µVrms for the MF6-100. For ±2.5V supplies the dynamic range is referenced to 1.06 Vrms (1.5V peak) where the wideband noise over a 20 kHz bandwidth is typically 140 µVrms for both the MF6-50 and the MF6-100. Note 3: The specifications for the MF6 have been given for a clock frequency (fCLK) of 250 kHz and less. Above this clock frequency the cutoff frequency begins to deviate from the specified error band of ±1.0% but the filter still maintains its magnitude characteristics.
