ADVANCED LINEAR DEVICES, INC. ALD4702A/ALD4702B ALD4702 QUAD 5V RAIL-TO-RAIL PRECISION OPERATIONAL AMPLIFIER GENERAL DESCRIPTION The ALD4702A/ALD4702B/ALD4702 is a quad monolithic precision CMOS rail-to-rail operational amplifier intended for a broad range of analog applications using ±2.5V to ±5V dual power supply systems, as well as +4V to +10V battery operated systems. All device characteristics are specified for +5V single supply or ±2.5V dual supply systems. Total supply current for four operational amplifiers is 6mA maximum at 5V supply voltage. It is manufactured with Advanced Linear Devices' enhanced ACMOS silicon gate CMOS process. The ALD4702A/ALD4702B/ALD4702 is designed to offer a trade-off of performance parameters providing a wide range of desired specifications. It has been developed specifically with the +5V single supply or ±2.5V dual supply user andoffers the popular industry pin configuration of LM324 and ICL7641 types. Several important characteristics of the device make many applications easy to implement for these supply voltages. First, the operational amplifier can operate with rail to rail input and output voltages. This feature allows numerous analog serial stages to be implemented without losing operating voltage margin. Second, the device was designed to accommodate mixed applications where digital and analog circuits may work off the same 5V power supply. Third, the output stage can drive up to 400pF capacitive and 5KΩ resistive loads in non-in...
