Product Overview
The OPA4376 is a Texas Instruments quad precision operational amplifier for Signal_Chain designs. The device provides four amplifier channels in the OPA4376 quad version and operates from a recommended 2.2 V to 5.5 V supply. Its recommended ambient operating temperature range is -40 to 150 °C.
Precision parameters include 5 µV typical and 25 µV maximum input offset voltage at 25 °C, with offset drift specified as 0.26 µV/°C typical to +85 °C and 0.32 µV/°C typical to +125 °C. Input bias and offset currents are both 0.2 pA typical at 25 °C, and input voltage noise density is 7.5 nV/√Hz typical at 1 kHz.
The amplifier is supplied in a TSSOP-14 (PW) package with a 5.00 mm x 4.40 mm nominal body. Package-level data includes 107.8 °C/W junction-to-ambient thermal resistance for the OPA4376 PW TSSOP-14 package. The device is suited to precision signal conditioning, low-bias sensor interfaces, low-noise measurement stages, and multi-channel analog front ends based on its documented amplifier, noise, input, output, and supply specifications.
