8-SOIC footprint and board-level fit
The OPA344UA is a single-channel general-purpose operational amplifier in an 8-SOIC package (3.90 mm body width). The surface-mount footprint matches the standard SOIC-8 land pattern, and the 150 µA supply current keeps the thermal load low enough that no special copper pour or airflow is needed in a typical mixed-signal board.
Bandwidth and slew rate for signal-conditioning loops
With a 1 MHz gain-bandwidth product and 0.8 V/µs slew rate, this amplifier supports signal bandwidths up to roughly 100 kHz at a gain of 10 before the slew-rate limit distorts the output. The rail-to-rail output stage swings within 10 mV of either supply rail, preserving dynamic range in low-voltage single-supply chains.
Supply range and precision for battery-powered sensors
The OPA344UA operates from a 2.5 V to 5.5 V supply span, suiting it for 3.3 V or 5 V systems. Input bias current is 0.2 pA typical, and input offset voltage is 200 µV maximum — both figures matter for high-impedance sensor front-ends where the bias current drop across the source resistance would otherwise dominate the error budget.
Active lifecycle and compliance status
Texas Instruments lists the OPA344UA as Active with RoHS3 compliance.
