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_DD of 25 µA/amplifier, and 10 pA typical input bias current, the DS4802 is ideal
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.
