OPA345NA/250

Instrumentation, Op Amps, Buffer Amps Overview

The OPA345NA/250 is a single-channel, low-power operational amplifier from Texas Instruments. It features rail-to-rail input and output capabilities, making it suitable for single-supply applications. Key electrical parameters include a gain-bandwidth product of 3 MHz and a slew rate of 2 V/us. The device operates within a supply voltage range of 2.5 V to 5.5 V while consuming only 150 uA of operating supply current. It offers an input offset voltage of 1 mV and an input bias current of 10 pA. The component is housed in a SOT-23-5 package and supports surface mount installation.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix against official Texas Instruments documentation to confirm pinout and electrical specifications. Ensure the ordering part number matches the required package type and tape-and-reel quantity. Confirm RoHS compliance status through the manufacturer's latest datasheet before finalizing procurement orders.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when designing for low-voltage, single-supply environments requiring rail-to-rail performance. Compare the 3 MHz bandwidth and 150 uA current draw against system requirements. Consider the SOT-23-5 package constraints for thermal management and PCB layout space limitations in compact designs.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the OPA345 family of micro-power operational amplifiers. It shares architectural similarities with other members like the OPA345UA but differs in packaging. The family is designed for general-purpose analog signal processing where power efficiency and full output swing are critical design constraints.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The OPA345NA/3K is a documented substitute offering identical electrical characteristics in a different reel configuration. Verify that the alternative package variant meets the physical footprint requirements of the existing design.
