ADVANCED ALD2704A/ALD2704B LINEAR ALD2704 DEVICES, INC. DUAL RAIL-TO-RAIL CMOS OPERATIONAL AMPLIFIER GENERAL DESCRIPTION FEATURES The ALD2704A/ALD2704B/ALD2704 is a dual monolithic operational Rail-to-rail input and output voltage ranges amplifier with MOSFET input that has rail-to-rail input and output voltage Symmetrical push-pull output drives ranges. The input voltage range and output voltage range are very close Output settles to 2mV of supply rails to the positive and negative power supply voltages. Typically the input 5.0V/s slew rate + voltage can be beyond positive power supply voltage V or the negative High capacitive load capability -- up to 4000pF - power supply voltage V by up to 300mV. The output voltage swings to No frequency compensation required -- unity within 60mV of either positive or negative power supply voltages at rated gain stable load. Extremely low input bias currents -- <1.0pA typical (20pA max.) With high impedance load, the output voltage of the ALD2704A/ALD2704B/ Ideal for high source impedance applications ALD2704 approaches within 1mV of the power supply rails. This device High voltage gain -- typically 100V/mV is designed as an alternative to the popular J-FET input operational Output short circuit protected amplifier in applications where lower operating voltages, such as 9V Unity gain bandwidth of 2.1MHz battery or 3.25V to 5V power supplies are being used. The ALD2704A/ Suitable for rugged, temperature-extreme ALD2704B/ALD2704 offers high slew rate of 5V/s. It is designed and environments manufactured with Advanced Linear Devices standard enhanced ACMOS silicon gate CMOS process, and it offers low unit cost and exceptional APPLICATIONS reliability. Voltage amplifier The rail-to-rail input and output feature of the ALD2704A/ALD2704B/ Voltage follower/buffer ALD2704 expands signal voltage range for a given operating supply Charge integrator voltage and allows numerous analog serial stages to be implemented Photodiode amplifier without losing operating voltage margin. The output stage is designed to Data acquisition systems drive up to 10mA into 400pF capacitive and 1.5K resistive loads at unity High performance portable instruments gain and up to 4000pF at a gain of 5. Short circuit protection to either Signal conditioning circuits ground or the power supply rails is at approximately 15mA clamp current. Low leakage amplifiers Due to complementary output stage design, the output can source and Active filters sink 10mA into a load with symmetrical drive and is ideally suited for Sample/Hold amplifier applications where push-pull voltage drive is desired. Picoammeter Current to voltage converter For each of the operational amplifier, the offset voltage is trimmed on-chip Coaxial cable driver to eliminate the need for external nulling in many applications. For Capacitive sensor amplifier precision applications, the output is designed to settle to 0.1% in 2s. In Piezoelectric transducer amplifier large signal buffer applications, the operational amplifier can function as an ultrahigh input impedance voltage follower /buffer that allows input and output voltage swings from positive to negative supply voltages. This feature is intended to greatly simplify systems design and eliminate higher voltage power supplies in many applications. Additionally, robust design PIN CONFIGURATION and rigorous screening make this device especially suitable for operation in temperature-extreme environments and rugged conditions. + 1 8 OUT V A ORDERING INFORMATION (L suffix denotes lead-free (RoHS)) Operating Temperature Range -IN 2 7 OUT A B 0C to +70C0C to +70C -55C to 125C +IN 3 6 -IN A B 8-Pin 8-Pin 8-Pin Small Outline Plastic Dip CERDIP - V 4 5 +IN B Package (SOIC) Package Package ALD2704ASAL ALD2704APAL ALD2704ADA TOP VIEW SAL, PAL, DA PACKAGES ALD2704BSAL ALD2704BPAL ALD2704BDA ALD2704SAL ALD2704PAL ALD2704DA * Contact factory for leaded (non-RoHS) or high temperature versions.
