Typical Application
Figure 3. Typical Application
These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.

(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 rated operating conditions.
(2) When the input voltage (V
I
) at any pin exceeds the power supplies (V
I
< GND or V
I
> +V
S
) the current at that pin should be limited to 5
mA. The 20 mA maximum 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.
(3) Human body model, 100 pF discharged through a 1.5 kΩ resistor. Machine model, 200 pF discharged directly into each pin.
(4) Reflow temperature profiles are different for lead-free and non-lead-free packages.

(2) LM77 θ
JA
(thermal resistance, junction-to-ambient) when attached to a printed circuit board with 2 oz. foil is: 200°C/W for the SOIC-8
(D0008A) package, 250°C/W for the VSSOP-8 (DGK0008A) package.
(3) While the LM77 has a full-scale-range in excess of 128°C, prolonged operation at temperatures above 125°C is not recommended.
(4) Both part numbers of the LM77 will operate properly over the +V
S
supply voltage range of 3V to 5.5V . The devices are tested and
specified for rated accuracy at their nominal supply voltage. Accuracy will typically degrade 1°C/V of variation in +V
S
as it varies from
the nominal value.
