GENERAL DESCRIPTION
The ADA4096-2 operational amplifier features micropower
operation and rail-to-rail input and output ranges. The
extremely low power requirements and guaranteed operation
from 3 V to 30 V make these amplifiers perfectly suited to
monitor battery usage and to control battery charging. Their
dynamic performance, including 27 nV/√Hz voltage noise
density, recommends them for battery-powered audio applications. Capacitive loads to 200 pF are handled without oscillation.
The ADA4096-2 has overvoltage protection inputs and diodes
that allow the voltage input to extend 32 V above and below
the supply rails, making this device ideal for robust industrial
applications.
The ADA4096-2 features a unique input stage that allows the
input voltage to exceed either supply safely without any phase
reversal or latch-up; this is called overvoltage protection, or OVP.
The dual ADA4096-2 is available in 8-lead LFCSP (2 mm × 2 mm)
and 8-lead MSOP packages. The ADA409x family is specified
over the extended industrial temperature range (−40°C to +125°C)
and is part of the growing selection of 30 V, low power op amps
from Analog Devices, Inc. (see Table 1).

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).
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
Ratings section, Table 5. Figure 46 shows the ADA4096-2 in a
unity-gain configuration with the input signal at ±40 V and the
amplifier supplies at ±10 V.
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
Table 4).
T
1
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.

INPUT OVERVOLTAGE PROTECTION
The ADA4096-2 inputs are protected from input voltage
excursions up to 32 V outside each rail. This feature is of
particular importance in applications with power supply
sequencing issues that could cause the signal source to be active
before the supplies to the amplifier.

Figure 47 shows the input current limiting capability of the
ADA4096-2 (green curves) compared to using a 5 kΩ series
resistor (red curves).
Figure 47 was generated with the ADA4096-2 in a buffer configuration with the supplies connected to GND (or ±15 V) and the
positive input swept until it exceeds the supplies by 32 V. In general,
input current is limited to 1 mA during positive overvoltage conditions and 200 μA during negative undervoltage conditions. For
example, at an overvoltage of 20 V, the ADA4096-2 input current is
limited to 1 mA, providing a current limit equivalent to a series
20 kΩ resistor. Figure 47 also shows that the current limiting
circuitry is active whether the amplifier is powered or not.

Although op amps are quite different from comparators,
occasionally an unused section of a dual or a quad op amp
may be pressed into service as a comparator; however, this is
not recommended for any rail-to-rail output op amps. For railto-rail output op amps, the output stage is generally a ratioed
current mirror with bipolar or MOSFET transistors. With the part
operating open loop, the second stage increases the current drive
to the ratioed mirror to close the loop, but it cannot, which results
in an increase in supply current. With the op amp configured as
a comparator, the supply current can be significantly higher (see
Figure 48).
