The Texas Instruments OPA353NA/3K is a single-channel high-speed CMOS operational amplifier featuring rail-to-rail input and output (RRIO) operation. It supports a 2.7V to 5.5V supply range, provides a typical 44MHz gain-bandwidth product, and offers a typical 22V/µs slew rate. These characteristics make it suitable for ADC driving, data acquisition, video processing, communications, active filters, and general high-speed analog signal conditioning.
TI lists typical input voltage noise density at 7nV/√Hz, maximum input offset voltage at 8mV at 25°C, and typical offset drift at 5µV/°C. Maximum input bias current is 10pA, while typical quiescent current is 5.2mA per channel.
The OPA353 is unity-gain stable and provides rail-to-rail signal capability. With a light resistive load, its output can typically swing to within approximately 10mV of the supply rails, helping maximize dynamic range in low-voltage analog systems.
The exact OPA353NA/3K orderable part is supplied in a 5-pin SOT-23 (DBV) package, operates from -40°C to +85°C, and is packaged in 3,000-piece large tape-and-reel quantities. TI currently lists the device as ACTIVE, RoHS compliant, and REACH compliant.
