Typical performance of the instrumentation amplifier:
Input offset voltage = 0.8mV
Input bias current = 320pA
Input offset current = 10pA
Input resistance = 1011
Input noise = 3.4
VP-P
High Speed Operation
The low noise performance of the LT1113 was achieved by
making the input JFET differential pair large to maximize
the first stage gain. Increasing the JFET geometry also
increases the parasitic gate capacitance, which if left
unchecked, can result in increased overshoot and ringing.
When the feedback around the op amp is resistive (RF),
a pole will be created with RF, the source resistance and
capacitance (RS,CS), and the amplifier input capacitance
(CIN = 27pF). In closed loop gain configurations and
with RS and RF in the kilohm range (Figure 5), this pole
can create excess phase shift and even oscillation.
A small capacitor (CF) in parallel with RF eliminates this
problem. With RS(CS + CIN) = RFCF, the effect of the
feedback pole is completely removed.
Figure 5.
The concepts of common mode and power supply
rejection ratio match (
CMRR and PSRR) are best
demonstrated with a numerical example:
Assume CMRRA = +50V/V or 86dB,
and CMRRB = + 39V/V or 88dB,
then
CMRR = 11V/V or 99dB;
if CMRRB = -39V/V which is still 88dB,
then
CMRR = 89V/V or 81dB
Clearly the LT1113, by specifying and guaranteeing all of
these matching parameters, can significantly improve the
performance of matching-dependent circuits.
