ALD1701G

The ALD1701 is a monolithic CMOS micropower high slew rate operational amplifier intended for a broad range of analog applications using ±1V to ±6V dual power supply systems, as well as +2V to +12V battery operated systems. All device characteristics are specified for +5V single supply or ±2.5V dual supply systems. Supply current is 250mA maximum at 5V supply voltage. It is manufactured with Advanced Linear Devices' enhanced ACMOS silicon gate CMOS process.

The ALD1701 is designed to offer a trade-off of performance parameters providing a wide range of desired specifications. It offers the popular industry standard pin configuration of mA741 and ICL7611 types.

The ALD1701 has been developed specifically for the +5V single supply or ±1V to ±6V dual supply user. Several important characteristics of the device make application easier to implement at those voltages.

First, the 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 the positive and negative supply voltages. This feature allows numerous analog serial stages and flexibility in input signal bias levels. Secondly, ALD1701 was designed to accommodate mixed applications where digital and analog circuits may operate off the same power supply or battery. Thirdly, the output stage can typically drive up to 50pF capacitive and 10KW resistive loads.

These features, combined with extremely low input currents, high open loop voltage gain of 100V/mV, useful bandwidth of 700KHz, a slew rate of 0.7V/ms, low power dissipation of 0.5mW, low offset voltage and temperature drift, make the ALD1701 a versatile, micropower operational amplifier.

The ALD1701, designed and fabricated with silicon gate CMOS technology, offers 1pA typical input bias current. On chip offset voltage trimming allows the device to be used without nulling in most applications.
