The ADA4091-2ACPZ-RL dual and ADA4091-4 quad are micropower,single-supply, 1.2 MHz bandwidth amplifiers featuring rail-torailinputs 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 Vdual supplies.
The ADA4091-2ACPZ-RL / ADA4091-4 features a unique input stage thatallows the input voltage to exceed either supply safely without anyphase reversal or latch-up; this is called overvoltage protection(OVP).
Applications for these amplifiers include portable telecommunicationsequipment, power supply control and protection,and interface for transducers with wide output ranges. Sensorsrequiring a rail-to-rail input amplifier include Hall effect, piezoelectric,and resistive transducers.
The ability to swing rail-to-rail at both the input and output enablesdesigners, for example, to build multistage filters in single-supplysystems and to maintain high signal-to-noise ratios (SNR).
The ADA4091-2ACPZ-RL / ADA4091-4 is specified over the extended industrialtemperature range of −40°C to +125°C. The ADA4091-2ACPZ-RL /ADA4091-4 is part of the growing selection of 36 V, low poweroperational amplifiers from Analog Devices, Inc.,
The ADA4091-2ACPZ-RL is available in 8-lead, plastic SOIC and 8-leadLFCSP packages. The ADA4091-4 is available in 14–lead TSSOPand 16-lead LFCSP surface-mount packages.
