New Instrumentation Amplifiers Maximize Output Swing
on Low Voltage Supplies вЂ“ Design Note 323
Glen Brisebois
INTRODUCTION
Instrumentation ampliп¬Ѓers suffer from a chronic output
swing problem, even when the input common mode
range and output voltage swing speciп¬Ѓcations are not
violated. This is because the п¬Ѓrst stage of an instrumentation ampliп¬Ѓer has internal output voltages that can
clip at unspeciп¬Ѓed levels. The clipping itself is invisible
to the user, but it affects the output swing adversely,
usually causing a gain reduction and thus an invalid
result. The new LTC В®6800 and LTВ®1789-10 both solve
this output swing problem, but in two extremely different ways. The LTC6800 incorporates a п¬‚ying capacitor
differential level shifter followed by a rail-to-rail output
autozero ampliп¬Ѓer. The LT1789-10 is a more classical
three op amp instrumentation ampliп¬Ѓer with the twist
that it takes gain in the п¬Ѓnal stage.
A CLEARER PICTURE OF THE PROBLEM
Figure 1 shows the classical three op amp instrumentation ampliп¬Ѓer (IA) topology. Assume that the op amps
involved can common mode to VS вЂ“ and have rail-to-rail
output stages. This would normally mean that the inputs
can be anywhere from VS вЂ“ to about a volt from VS+ and
that the output can be anywhere within the supply rails. …
