3. The input bias and offset currents are essentially input protection
amplifier uses a 3 gain stage architecture and an improved frequency
compensation scheme to achieve large voltage gain, high output
driving capability, and better frequency stability. In a conventional
CMOS operational amplifier design, compensation is achieved with
a pole splitting capacitor together with a nulling resistor. This method
is, however, very bias dependent and thus cannot accommodate the
large range of supply voltage operation as is required from a stand
alone CMOS operational amplifier.
ALD1701/ALD1701G is internally compensated for unity gain stability
using a novel scheme that does not use a nulling resistor. This
scheme produces a clean single pole roll off in the gain characteris-
tics while providing for more than 70 degrees of phase margin at the
unity gain frequency.
tary p-channel and n-channel input differential stages connected in
parallel to accomplish rail to rail input common mode voltage range.
This means that with the ranges of common mode input voltage close
to the power supplies, one of the two differential stages is switched
off internally. To maintain compatibility with other operational ampli-
fiers, this switching point has been selected to be about 1.5V below
the positive supply voltage. Since offset voltage trimming on the
ALD1701A/ALD1701B/ALD1701/ALD1701G is made when the input
voltage is symmetrical to the supply voltages, this internal switching
does not affect a large variety of applications such as an inverting
amplifier or non-inverting amplifier with a gain larger than 2.5 (5V
operation), where the common mode voltage does not make excur-
sions above this switching point. The user should however, be aware
that this switching does take place if the operational amplifier is
connected as a unity gain buffer, and should make provision in his
design to allow for input offset voltage variations.

capable of driving a low resistance load. The output voltage swing is
limited by the drain to source on-resistance of the output transistors
as determined by the bias circuitry, and the value of the load resistor.
When connected in the voltage follower configuration, the oscillation
resistant feature, combined with the rail to rail input and output
feature, makes an effective analog signal buffer for medium to high
source impedance sensors, transducers, and other circuit networks.
fier has been designed to provide full static discharge protection.
Internally, the design has been carefully implemented to minimize
latch up. However, care must be exercised when handling the device
to avoid strong static fields that may degrade a diode junction, causing
increased input leakage currents. In using the operational amplifier,
the user is advised to power up the circuit before, or simultaneously
with any input voltages applied, and to limit input voltages not to
exceed 0.3V of the power supply voltage levels.
micropower operation, offers numerous benefits in reduced power
supply requirements, less noise coupling and current spikes, less
thermally induced drift, better overall reliability due to lower self
heating, and lower input bias current. It requires practically no warm
up time as the chip junction heats up to only 0.1°C above ambient
temperature under most operating conditions.
