Answer / nithya.s

op amp is selected triangular in shape because it has two
terminals as inverting and noninverting and having only one
output common for both the terminal.if in case we also
provide an feedback if nessesary.if it is selected as any
other shape,it is not possible.

Answer / rajasekhar

it is unidirectional device.

Answer / purohit nirav

hey raj......it is a important question interview point of
view so people focusing it

Answer / purohit nirav

because op-amp has a high input impedance and low output
impedance

Answer / raj

hi ..unidirectional property is the correct ans......

Answer / jayesh pakahle

Because Opamp has two inputs while only one output.

Answer / n.rajasekhar

nothing fancy there,just to show that it will unidirectional
gain.infact there are fully differential opamps(which can
have 2i/p and 2o/p),for this also triangler.

Answer / girish

The tapering edge of the triangle shows the direction of the
current flow in the Op-Amp.
Correct me if I am wrong

Answer / raj

its wrong, there are fully-differential opamps which has 2
inputs and 2outputs..still its shape is like triangle.
mainly that shape indicated its reverse transmission is less

Answer / farah

because in op-amp we hav 2 input&1 output, so the structure is like that.
correct me if am wrong.
