ORDERING INFORMATION
DESCRIPTION
The DS4802 BiCMOS dual operational amplifier combines low input offset voltage, very low power
consumption, rail-to-rail output swing, and excellent DC precision. With a maximum input offset voltage
of 0.95 mV, a maximum I
for measurement, medical, and industrial applications. The DS4802 is also ideal for portable applications
with 1.8 volt to 5.5 volt single supply voltage operation and low power consumption.
For mechanical dimensions see website.
