OPA4704EA/250

Instrumentation, Op Amps, Buffer Amps Overview

The OPA4704EA/250 is a quad operational amplifier from Texas Instruments, featuring CMOS rail-to-rail input and output capabilities. It operates within a supply voltage range of 3 V to 12 V, with a maximum dual supply of 6 V. Key electrical parameters include a gain-bandwidth product of 3 MHz, a slew rate of 3 V/us, and an input bias current of 10 pA. The device offers a common-mode rejection ratio of 90 dB and an input voltage noise density of 45 nV/sqrt Hz. Each channel provides an output current of 10 mA, while the operating supply current is 160 uA. It is housed in a TSSOP-14 package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix EA/250 against the manufacturer's official datasheet to confirm the TSSOP-14 packaging and reel specifications. Ensure compatibility with your PCB footprint and reflow soldering profile. Cross-reference the part number with authorized distributors to validate authenticity and traceability before procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a quad configuration with rail-to-rail I/O is required alongside moderate bandwidth. Compare its 3 MHz gain-bandwidth product and 10 pA input bias current against alternatives if higher speed or lower noise is needed. Consider the 160 uA supply current relative to power-constrained designs.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the OPA470x family of low-cost, general-purpose operational amplifiers. It shares architectural similarities with other members like the OPA4703 and OPA4705 but differs in specific performance metrics such as slew rate and offset voltage. The family targets cost-sensitive applications requiring reliable analog signal processing.
