Figure 45. Simplified Schematic
Figure 45 shows a simplified schematic of the ADA4096-2. The
input stage comprises two differential pairs (Q1 to Q4 and Q5
to Q8) operating in parallel. When the input common-mode
voltage approaches VCC 1.5 V, Q1 to Q4 shut down as I1 reaches
its minimum voltage compliance. Conversely, when the input
common-mode voltage approaches VEE + 1.5 V, Q5 to Q8 shut
down as I2 reaches its minimum voltage compliance. This
topology allows for maximum input dynamic range because the
amplifier can function with its inputs at 200 mV outside the rail
(at room temperature).
As with any rail-to-rail input amplifier, VOS mismatch between
the two input pairs determines the CMRR of the amplifier. If
the input common-mode voltage range is kept within 1.5 V of
each rail, transitions between the input pairs are avoided, thus
improving the CMRR by approximately 10 dB (see Table 3 and
PHASE INVERSION
Some single-supply amplifiers exhibit phase inversion when
the input signal extends beyond the common-mode voltage
range of the amplifier. When the input devices become saturated,
the inverting and noninverting inputs exchange functions,
causing the output to move in the opposing direction.
Although phase inversion persists for only as long as the inputs are
saturated, it can be detrimental to applications where the amplifier
is part of a closed-loop system. The ADA4096-2 is free from phase
inversion over the entire common-mode voltage range, as well as
the overvoltage protected range stated in the Absolute Maximum
unity-gain configuration with the input signal at ±40 V and the
amplifier supplies at ±10 V.
