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 INA 1 12 IND dual supplies. 2 11 +INA ADA4091-4 +IND The ADA4091-2/ADA4091-4 features a unique input stage that TOP 10 V+ 3 V VIEW allows the input voltage to exceed either supply safely without any +INB 4 9+INC 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, NOTES 1.

IT IS RECOMMENDED TO CONNECT THE EXPOSED PAD TO V. requiring a rail-to-rail input amplifier include Hall effect, piezo- Figure 4. 16-Lead LFCSP (CP-16-17) electric, and resistive transducers. The ADA4091-2 is available in 8-lead, plastic SOIC and 8-lead The ability to swing rail-to-rail at both the input and output enables LFCSP packages. The ADA4091-4 is available in 14lead TSSOP designers, for example, to build multistage filters in single-supply and 16-lead LFCSP surface-mount packages. systems and to maintain high signal-to-noise ratios (SNR). The ADA4091-2/ADA4091-4 is specified over the extended indus- Table 1. Low Power, 36 V Operational Amplifiers trial temperature range of 40C to +125C.
