GENERAL DESCRIPTION
The ADA4092-4 quad is a micropower, single-supply, 1.2 MHz
bandwidth amplifier featuring rail-to-rail inputs and outputs. It
is guaranteed to operate from a +2.7 V to +30 V single supply as
well as from ±1.35 V to ±15 V dual supplies.
The ADA4092-4 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 (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 ADA4092-4 is specified over the extended industrial
temperature range of −40°C to +125°C. The ADA4092-4 is
part of the growing selection of 36 V, low power op amps from
Analog Devices, Inc., see Table 1.
The ADA4092-4 is available in the 14–lead TSSOP surface-mount
package.
