Amplifier Characteristics
Figure 1 shows a simplified schematic of the LT6202/
LT6203/LT6204, which has two input differential ampli-
fiers in parallel that are biased on simultaneously when
the common mode voltage is at least 1.5V from either
rail. This topology allows the input stage to swing from
the positive supply voltage to the negative supply voltage.
As the common mode voltage swings beyond VCC – 1.5V,
current source I1 saturates and current in Q1/Q4 is zero.
Feedback is maintained through the Q2/Q3 differential
amplifier, but with an input gm reduction of 1/2. A similar
effect occurs with I2 when the common mode voltage
swings within 1.5V of the negative rail. The effect of the
gm reduction is a shift in the VOS as I1 or I2 saturate.
APPLICATIONS INFORMATION
Input bias current normally flows out of the + and – inputs.
The magnitude of this current increases when the input
common mode voltage is within 1.5V of the negative rail,
and only Q1/Q4 are active. The polarity of this current
reverses when the input common mode voltage is within
1.5V of the positive rail and only Q2/Q3 are active.
The second stage is a folded cascode and current mir-
ror that converts the input stage differential signals to a
single ended output. Capacitor C1 reduces the unity cross
frequency and improves the frequency stability with-
out degrading the gain bandwidth of the amplifier. The
differential drive generator supplies current to the output
transistors that swing from rail-to-rail.
