■ DESCRIPTIO The LT®1794 is a 500mA minimum output current, dual op
amp with outstanding distortion performance. The amplifiers are gain-of-ten stable, but can be easily compensated
for lower gains. The extended output swing allows for
lower supply rails to reduce system power. Supply current
is set with an external resistor to optimize power dissipation. The LT1794 features balanced, high impedance inputs with low input bias current and input offset voltage.
Active termination is easily implemented for further system power reduction. Short-circuit protection and thermal
shutdown insure the device’s ruggedness. Exceeds All Requirements For Full Rate,
