LOW-NOISE, PRECISION OPERATIONAL AMPLIFIER

DESCRIPTION

The UTC OP27 precision operational amplifier combines the

low offset and drift of the OP07 with both high speed and low

noise. A gain-bandwidth product of 8MHz and a 1.9V/µsec slew

rate provides excellent dynamic accuracy in high-speed,

data-acquisition systems.

A low input bias current of ±80nA is achieved by use of a

bias-current-cancellation circuit. Over the military temperature

range, this circuit typically holds IB and IOS to ±25nA and 20nA,

respectively.

The output stage has good load driving capability. A

guaranteed swing of ±10V into 600Ω and low output distortion

make the UTC OP27 an excellent choice for professional audio

applications
