Supply current is 500A maximum at 5V supply voltage. It is Dual power supply 1.0V to 5.0V manufactured with Advanced Linear Devices enhanced ACMOS silicon gate CMOS process. Single power supply +2V to +10V High voltage gain The ALD2701A/ALD2701B/ALD2701 is designed to offer a trade-off of Output short circuit protected performance parameters providing a wide range of desired specifications. Unity gain bandwidth of 0.7MHz It has been developed specifically for the +5V single supply or 1V to Slew rate of 0.7V/s 5V dual supply user and offers the popular industry standard pin Low power dissipation configuration of A741 and ICL7621 types. Symmetrical output drive Suitable for rugged, temperature-extreme Several important characteristics of the device make application easier environments to implement at those voltages. First, each operational amplifier can operate with rail-to-rail input and output voltages. This means the signal APPLICATIONS input voltage and output voltage can be equal to the positive and negative supply voltages. This feature allows numerous analog serial stages and Voltage follower/buffer/amplifier flexibility in input signal bias levels. Second, each device was designed Charge integrator to accommodate mixed applications where digital and analog circuits Photodiode amplifier may operate off the same power supply or battery. Third, the output Data acquisition systems stage can typically drive up to 50pF capacitive and 10K resistive loads. High performance portable instruments Signal conditioning circuits These features, combined with extremely low input currents, high open Sensor and transducer amplifiers loop voltage gain of 100V/mV, useful bandwidth of 700KHz, a slew rate Low leakage amplifiers of 0.7V/s, low power dissipation of 0.5mW, low offset voltage and temperature drift, make the ALD2701A/ALD2701B/ALD2701 a versatile, Active filters micropower dual operational amplifier. Sample/Hold amplifier Picoammeter The ALD2701A/ALD2701B/ALD2701, designed and fabricated with Current to voltage converter 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. Due to low voltage and low power operation, reliability and operating characteristics, such as input bias currents and warm up time, are greatly PIN CONFIGURATION improved. Additionally, robust design and rigorous screening make this device especially suitable for operation in temperature-extreme environments and rugged conditions. + 8 OUT 1 V A -IN 2 7 OUT ORDERING INFORMATION (L suffix denotes lead-free (RoHS)) A B Operating Temperature Range +IN 3 6 -IN A B 0C to +70C0C to +70C -55C to 125C - V 4 5 +IN B 8-Pin 8-Pin 8-Pin Small Outline Plastic Dip CERDIP TOP VIEW Package (SOIC) Package Package SAL, PAL, DA PACKAGES ALD2701ASAL ALD2701APAL ALD2701ADA ALD2701BSAL ALD2701BPAL ALD2701BDA ALD2701SAL ALD2701PAL ALD2701DA * Contact factory for leaded (non-RoHS) or high temperature versions.
