ADVANCED ALD2702A/ALD2702B LINEAR ALD2702 DEVICES, INC. DUAL 5V RAIL-TO-RAIL PRECISION OPERATIONAL AMPLIFIER FEATURES GENERAL DESCRIPTION The ALD2702A/ALD2702B/ALD2702 is a dual monolithic operational Rail-to-rail input and output voltage ranges amplifier intended primarily for a wide range of analog applications in +5V Symmetrical push-pull class AB output single power supply and 5V dual power supply systems as well as +4V drivers All parameters specified for +5V single to +10V battery operated systems. All device characteristics are specified supply or 2.5V dual supply systems for +5V single supply or 2.5V dual supply systems. The device has an High load capacitance capability -- drives input stage that operates to +300mV above and -300mV below the supply voltages with no adverse effects and/or phase reversals. It offers popular up to 4000pF typical industry pin configuration. No frequency compensation required -- unity gain stable The ALD2702A/ALD2702B/ALD2702 has been developed specifically Extremely low input bias currents -- with the +5V single supply or 2.5V dual supply user in mind. Several <1.0pA typical Ideal for high source impedance applications important characteristics of the device make many applications easy to Dual power supply 2.5V to 5V operation implement for these supply voltages. First, the operational amplifier can Single power supply +5V to +10V operation operate with rail to rail input and output voltages. This feature allows High voltage gain -- typically 85V/mV numerous analog serial stages to be implemented without losing operating voltage margin. Second, the device was designed to accommodate 2.5V and 250V/mV 5.0V mixed applications where digital and analog circuits may work off the Drive as low as 2K load with 5mA same 5V power supply. Third, the output stage can drive up to 400pF drive current capacitive and 5K resistive loads in non-inverting unity gain connection Output short circuit protected Unity gain bandwidth of 1.5MHz and double the capacitance in the inverting unity gain mode. Slew rate of 1.9V/s Low power dissipation These features, coupled with extremely low input currents, high voltage gain, useful bandwidth of 1.5MHz, a slew rate of 1.9V/s, low power Suitable for rugged, temperature-extreme dissipation, low offset voltage and temperature drift, make the ALD2702A/ environments ALD2702B/ALD2702 a truly versatile, user friendly, operational amplifier. APPLICATIONS The ALD2702A/ALD2702B/ALD2702 is designed and fabricated with Voltage follower/buffer silicon gate CMOS technology, and offers less than 1pA typical input bias Charge integrator current. On-chip offset voltage trimming allows the device to be used Photodiode amplifier without nulling in most applications. The device offers typical offset drift Data acquisition systems of less than 7V/C which eliminates many trim or temperature High performance portable instruments compensation circuits. For precision applications, the ALD2702A/ Signal conditioning circuits ALD2702B/ALD2702 is designed to settle to 0.01% in 8s. Additionally, Sensor and transducer amplifiers robust design and rigorous screening make this device especially suitable Low leakage amplifiers for operation in temperature-extreme environments and rugged conditions.
