GENERAL DESCRIPTION
single-supply, 1.2 MHz bandwidth amplifiers featuring rail-to-
rail inputs and outputs. They are guaranteed to operate from a
+3.0 V to +30 V single supply as well as from ±1.5 V to ±15 V
dual supplies.
The ADA4091 family 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.
Applications for these amplifiers include portable telecom-
munications equipment, power supply control and protection,
and interface for transducers with wide output ranges. Sensors
requiring a rail-to-rail input amplifier include Hall effect, piezo-
electric, and resistive transducers.
The ability to swing rail-to-rail at both the input and output enables
designers, for example, to build multistage filters in single-supply
systems and to maintain high signal-to-noise ratios (SNR).
The ADA4091 family is specified over the extended industrial
temperature range of 40°C to +125°C. The ADA4091 family is
part of the growing selection of 36 V, low power op amps from
Analog Devices, Inc., (see Table 1).
