OPA376 OPA2376 OPA4376 SBOS406F – JUNE 2007 – REVISED MARCH 2013 www.ti.com APPLICATION INFORMATION 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 (5μV, typ).

OPA376 OPA2376 OPA4376 www.ti.com SBOS406F – JUNE 2007 – REVISED MARCH 2013 INPUT AND ESD PROTECTION The OPA376 family incorporates internal electrostatic discharge (ESD) protection circuits on all pins. In the case of input and output pins, this protection primarily consists of current steering diodes connected between the input and power-supply pins.

OPA376 OPA2376 OPA4376 SBOS406F – JUNE 2007 – REVISED MARCH 2013 www.ti.com OPA2376 WCSP PACKAGE The OPA2376YZD is a lead- (PB-) free, die-level, wafer chip-scale package (WCSP). Unlike devices that are in plastic packages, these devices have no molding compound, lead frame, wire bonds, or leads. Using standard surface-mount assembly procedures, the WCSP can be mounted to a PCB without additional underfill. Figure 27 and Figure 28 detail the pinout and package marking.
