Typical Application

The OPA376 family of operational amplifiers is built using e-trim , a proprietary technique in which offset voltage is adjusted during the final steps of manufacturing. This technique compensates for performance shifts that can occur during the molding process. Through e-trim , the OPA376 family delivers excellent offset voltage (5 μ V, typical). Additionally, the amplifier boasts a fast slew rate, low drift, low noise, and excellent PSRR and AOL. These 5.5-MHz CMOS op amps operate on 760μ A (typical) quiescent current.
