MICROPOWER RAIL-TO-RAIL CMOS OPERATIONAL AMPLIFIER  
GENERAL DESCRIPTION  
FEATURES  
TheALD1701isamonolithicCMOSmicropowerhighslewrateoperational  
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 250µA maximum at 5V  
supply voltage. It is manufactured with Advanced Linear Devices' en-  
hanced ACMOS silicon gate CMOS process.  
• All parameters specified for +5V single  
supply or ±2.5V dual supply systems  
• Rail to rail input and output voltage ranges  
• No frequency compensation required --  
unity gain stable  
• Extremely low input bias currents --  
1.0pA typical (30pA max.)  
• Ideal for high source impedance  
applications  
• Dual power supply ±1.0V to ±6.0V operation  
• Single power supply +2V to +12V operation  
• High voltage gain -- typically 100V/mV  
@ ±2.5V(100dB)  
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 µA741 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.  
• Drive as low as 10Kload  
• Output short circuit protected  
• Unity gain bandwidth of 0.7MHz  
• Slew rate of 0.7V/µs  
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, the device was designed to accommodate mixed applications  
where digital and analog circuits may operate off the same power supply  
orbattery. Thirdly,theoutputstagecantypicallydriveupto50pFcapacitive  
and 10Kresistive loads.  
• Low power dissipation  
APPLICATIONS  
• Voltage amplifier  
• Voltage follower/buffer  
• Charge integrator  
• Photodiode amplifier  
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/µs, low power dissipation of 0.5mW, low offset voltage and tempera-  
ture drift, make the ALD1701 a versatile, micropower operational amplifier.  
• Data acquisition systems  
• High performance portable instruments  
• Signal conditioning circuits  
• Sensor and transducer amplifiers  
• Low leakage amplifiers  
• Active filters  
The ALD1701, designed and fabricated with silicon gate CMOS techno-  
logy, offers 1pA typical input bias current. On chip offset voltage trimming  
allows the device to be used without nulling in most applications.  
• Sample/Hold amplifier  
• Picoammeter  
• Current to voltage converter
