Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. DC and AC electrical specifications do not apply when operating

the device beyond its specified operating conditions.

Note 2: When the input voltage (VIN) at any pin exceeds the power supply rails (VIN < V

− or V

IN > V

+) the absolute value of current at that pin should be limited

to 5 mA or less. The 20 mA package input current limits the number of pins that can exceed the power supply boundaries witha5mA current limit to four.

Note 3: The maximum power dissipation must be derated at elevated temperatures and is dictated by TJMAX, θJA, and the ambient temperature, TA. The maximum

allowable power dissipation at any temperature is PD =(TJMAX −TA)/θJA or the number given in the Absolute Maximum Ratings, whichever is lower. For this device,

TJMAX = 125˚C, and the typical junction-to-ambient thermal resistance of the MF10ACN/CCN when board mounted is 55˚C/W. For the MF10AJ/CCJ, this number

increases to 95˚C/W and for the MF10ACWM/CCWM this number is 66˚C/W.

Note 4: The accuracy of the Q value is a function of the center frequency (fO). This is illustrated in the curves under the heading “Typical Performance

Characteristics”.

Note 5: VOS1,VOS2, and VOS3 refer to the internal offsets as discussed in the Applications Information Section 3.4.

Note 6: For ±5V supplies the dynamic range is referenced to 2.82V rms (4V peak) where the wideband noise over a 20 kHz bandwidth is typically 200 µV rms for

the MF10 with a 50:1 CLK ratio and 280 µV rms for the MF10 with a 100:1 CLK ratio.

Note 7: The short circuit source current is measured by forcing the output that is being tested to its maximum positive voltage swing and then shorting that output

to the negative supply. The short circuit sink current is measured by forcing the output that is being tested to its maximum negative voltage swing and then shorting

that output to the positive supply. These are the worst case conditions.

Note 8: Typicals are at 25˚C and represent most likely parametric norm.

Note 9: Tested limits are guaranteed to National’s AOQL (Average Outgoing Quality Level).

Note 10: Design limits are guaranteed but not 100% tested. These limits are not used to calculate outgoing quality levels.

Note 11: Human body model, 100 pF discharged through a 1.5 k

Ω resistor.
