LM66 Electrical Characteristics
The following specifications apply for V
+ = 2.7 V
DC, and VREF load current = 50 µA unless otherwise specified. Boldface lim-
its apply for T
A =TJ =TMIN to TMAX; all other limits TA =TJ = 25˚C unless otherwise specified.

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is func-
tional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. The guaranteed speci-
fications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed test conditions.
Note 2: When the input voltage (VI) at any pin exceeds the power supply (VI < GND or VI > V
+), the current at that pin should be limited to 5 mA. The 20 mA maxi-
mum package input current rating limits the number of pins that can safely exceed the power supplies with an input current of 5 mA to four.
Note 3: The maximum power dissipation must be derated at elevated temperatures and is dictated by TJmax (maximum junction temperature), θJA (junction to am-
bient thermal resistance) and TA (ambient temperature). 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. For this device the typical thermal resistance (θJA) of the different package
types when board mounted follow:
Package Type
θ
JA
M08A
110˚C/W
Note 4: The human body model is a 100 pF capacitor discharge through a 1.5 k
Ω resistor into each pin. The machine model is a 200 pF capacitor discharged directly
into each pin.
Note 5: See AN450 “Surface Mounting Methods and Their Effects on Product Reliability” or the section titled “Surface Mount” found in any post 1986 National Semi-
conductor Linear Data Book for other methods of soldering surface mount devices.
Note 6: Typicals are at TJ =TA = 25˚C and represent most likely parametric norm.
Note 7: Limits are guaranteed to National’s AOQL (Average Outgoing Quality Level).
