± 1A
Analog inputs, V_I
-0.3V to 6.3V
Error amp output sink current, I_SINK(EA)
10mA
Power dissipation (T_A = 25 ^OC), P_D
1W
Maximum juncture temperature, T_J
150 ^OC
Storage temperature range
-65^OC to 150^OC
Lead temperature (soldiering, 10 seconds)

Note 1: Exceeding these ratings could cause damage to the device. All voltages are with respect to Ground.
Currents are positive into, negative out of the specified terminal.
THERMAL DATA
M PACKAGE:
Thermal Resistance-Junction to Ambient, θ_JA
D PACKAGE:
Thermal Resistance-Junction to Ambient, θ_JA
DM PACKAGE:
Thermal Resistance-Junction to Ambient, θ_JA
Junction Temperature Calculation: T_J = T_A + (P_D × θ_JA).
The θ_JA numbers are guidelines for the thermal performance of the device/pc-board system.
All of the above assume no ambient airflow.
95 ^OC/W
120 ^OC/W
165 ^OC/W
