OPA344UA Description

Short technical summary and product information.

The OPA344UA from Texas Instruments is a single-channel, low-power operational amplifier designed for single-supply operation. It features rail-to-rail input and output capabilities, allowing for maximum dynamic range. With a gain-bandwidth product of 1MHz and a slew rate of 0.8V/µs, it is suitable for various audio and general-purpose applications.

This op-amp operates over a supply voltage range of 2.5V to 5.5V, with a typical quiescent current of 0.15mA per channel. The offset voltage is a maximum of 1mV at 25°C, and the offset drift is typically 3µV/°C. It maintains a typical Common Mode Rejection Ratio (CMRR) of 92dB and an input bias current of 1pA.

The OPA344UA is available in multiple package options including SOIC, PDIP, and SOT-23. Its operating temperature range is -40°C to 85°C. Applications include PCMCIA cards, data acquisition, process control, audio processing, communications, and active filters.
