Product Overview
Texas Instruments OPA2340 is a dual rail-to-rail operational amplifier for Signal_Chain designs requiring two amplifier channels in one package. The device provides rail-to-rail input and rail-to-rail output behavior, with output swing specified within 1 mV using a 100-kΩ load. Its input common-mode capability extends from 500 mV below ground to 500 mV above the positive supply during single-supply operation.
Core dynamic parameters include 5.5 MHz bandwidth or gain-bandwidth product and 6 V/µs slew rate. Electrical characteristics include ±150 µV typical input offset voltage, ±0.2 pA typical input bias current, 25 nV/√Hz input voltage noise density at 1 kHz, and 3 fA/√Hz current noise density at 1 kHz.
Package options for OPA2340 include 8-pin VSSOP, 8-pin SOIC, and 8-pin PDIP. Thermal resistance is specified as 138.4°C/W for the SOIC-8 D package and 169.2°C/W for the VSSOP-8 DGK package. Typical applications can include single-supply signal conditioning, active filtering, low-bias sensor interfaces, and audio-frequency analog stages.
