GENERAL DESCRIPTION  
The CBM8531, CBM8532, and CBM8534 are single, dual, and quad rail-to-rail input/output  
single-supply amplifiers featuring 250 mA 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 3 V single supply as well as a 5 V supply.  
The very low input bias currents enable the CBM853X 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.  
Applications include audio amplification for computers, sound ports, sound cards, and  
set-top boxes. The CBM853X family is very stable, and it is capable of driving heavy capacitive  
loads such as those found in LCDs.  
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 CBM8531/CBM8532/CBM8534 are specified over the extended industrial temperature  
range (−40°C to +85°C). The CBM8531 is available in 8-lead SOIC, 5-lead SC70, and 5-lead  
SOT-23 packages. The CBM8532 is available in 8-lead SOIC, 8-lead MSOP, and 8-lead TSSOP  
surface-mount packages. The CBM8534 is available in narrow 14-lead SOIC and 14-lead TSSOP  
surface-mount packages.
