Description
The CD8531, CD8532, and CD8534 are single, dual, and quad rail-to-rail input/output single-supply amplifiers featuring 250mA output drive current. This high output current makes these amplifiers excellent for driving either resistive or capacitive loads. AC performance is very good with 3 MHz bandwidth,5 V/μs slew rate, and low distortion. All are guaranteed to operate from a 2.7 V single supply as well as a 5.5 V supply. The very low input bias currents enable the CD8531, CD8532, and CD8534 to be used for integrators, diode amplification, and other applications requiring low input bias current. Supply current is only 750 μA per amplifier at 5 V, allowing low current applications to control high current loads. The ability to swing rail-to-rail at the inputs and outputs enables designers to buffer CMOS DACs, ASICs, or other wide output swing devices in single-supply systems.
The CD8531/CD8532/CD8534 are specified over the extended industrial temperature range (−40°C to +125°C).
The CD8531 is available in 8-lead SOIC, 5-lead SC70, and 5-lead SOT-23 packages.
The CD8532 is available in 8-lead SOIC, 8-lead MSOP, and 8-lead TSSOP surface-mount packages.
The CD8534 is available in narrow 14-lead SOIC and 14-lead TSSOP surface-mount packages.
