Advanced Linear Devices ALD4706PBL

The ALD4706A/ALD4706B/ALD4706 is a quad monolithic CMOS ultra micropower high slew-rate operational amplifier intended for a broad range of analog applications using ±1V to ±5V dual power supply systems, as well as +2V 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 200μA maximum at 5V supply voltage. It is manufactured with Advanced Linear Devices' enhanced ACMOS silicon gate CMOS process.

The ALD4706A/ALD4706B/ALD4706 is designed to offer a trade-off of performance parameters providing a wide range of desired specifications. It has been developed specifically for the +5V single supply or ±1V to ±5V dual supply user and offers the popular industry standard pin configuration of LM324 types and ICL7641 types.

Several important characteristics of the device make application easier to implement at these voltages. First, each operational amplifier can operate with rail-to-rail input and output voltages. This means the signal input voltage and output voltage can be equal to or near to the positive and negative supply voltages. This feature allows numerous analog serial stages and flexibility in input signal bias levels. Second, each device was designed to accommodate mixed applications where digital and analog circuits may operate off the same power supply or battery. Third, the output stage can typically drive up to 25pF capacitive and 20KΩ resistive loads. These features, combined with extremely low input currents, high open loop voltage gain of 100V/mV, useful bandwidth of 200KHz, a slew rate of 0.17V/μs, low power dissipation of 0.5mW, low offset voltage and temperature drift, make the ALD4706A/ALD4706B/ ALD4706 a versatile, ultra micropower quad operational amplifier.

The ALD4706A/ALD4706B/ALD4706, designed and fabricated with silicon gate CMOS technology, offers 0.1pA typical input bias current. Due to low voltage and low power operation, reliability and operating characteristics, such as input bias currents and warm up time, are greatly improved. Additionally, robust design and rigorous screening make this device especially suitable for operation in temperature-extreme environments and rugged conditions.
