The SP4010 is one kind of high accuracy,high speed,FET input buffer providing up to +-50 mA of continuous current at frequencies from DC to 60 MHz.High linearity,low offset,and excellent stability make it an ideal candidate for a high impedance input buffer for high resolution A/D converters.With a slew rate of 1000V/usec,good phase linearity and low distortion,the device is also well suited for a variety of video and high speed data acquisition applications.The SP4010 is specified for operation from 0 to +70 for commercial grade and -55 to +125 for miliyary grades.
The SP4010 is divided into the following circuit blocks:(1)signal FET source follower;(2)output buffer emitter follower;(3)DC bias FET and load regulation;(4)bias current mirror;(5)current feedback loop;(6)bootstrap.
Absolute maximum ratings of the SP4010 are:(1)supply voltage:+18 V or -18 V;(2)input voltage:Vsupply;(3)power dissipation:1 walt;(4)continuous output current:50 mA;(5)peak output current:100 mA;(6)operating temperature range:0 to +70;(7)operating junction temperature:150;(8)case to junction therma resistance:20/walt and (9)storage temperature:-65 to +125.
