LM759/LM77000 Power Operational Amplifiers
November 1994
LM759/LM77000
Power Operational Amplifiers
General Description
The LM759 and LM77000 are high performance operational
amplifiers that feature high output current capability. The
LM759 is capable of providing 325 mA and the LM77000
providing 250 mA. Both amplifiers feature small signal char-
acteristics that are better than the LM741. The amplifiers
are designed to operate from a single or dual power supply
with an input common mode range that includes the nega-
tive supply. The high gain and high output power provide
superior performance. Internal current limiting, thermal shut-
down, and safe area compensation are employed making
the LM759 and LM77000 essentially indestructible.

Note 1: Although the internal power dissipation is limited, the junction temperature must be kept below the maximum specified temperature in order to meet data
sheet specifications. To calculate the maximum junction temperature or heat sink required, use the thermal resistance values which follow the Equivalent Circuit
Schematic.
Note 2: For a supply voltage less than 30V between V
a
and V
b
, the absolute maximum input voltage is equal to the supply voltage.
Note 3: For military electrical specifications RETS759X are available for LM759H.
