The ADA4092-4 quad is a micropower, single-supply, 1.4 MHz The ADA4092-4 is specified over the extended industrial bandwidth amplifier featuring rail-to-rail inputs and outputs. It temperature range of −40°C to +125°C. The ADA4092-4 is is guaranteed to operate from a +3 V to +30 V single supply as part of the growing selection of 30 V, low power op amps from well as from ±1.5 V to ±15 V dual supplies. Analog Devices, Inc., see Table 1. The ADA4092-4 features a unique input stage that allows the The ADA4092-4 is available in the 14–lead TSSOP surface-mount input voltage to exceed either supply safely without any phase package. reversal or latch-up; this is called overvoltage protection (OVP).

and interface for transducers with wide output ranges. Sensors Single OP1177 requiring a rail-to-rail input amplifier include Hall effect, piezo- Dual ADA4091-2 AD8682 OP2177 electric, and resistive transducers. Quad ADA4092-4 ADA4091-4 AD8684 OP4177 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).
