OPA4703EA/250G4

Instrumentation, Op Amps, Buffer Amps Overview

The OPA4703EA/250G4 is a quad operational amplifier manufactured by Texas Instruments, featuring CMOS rail-to-rail input and output capabilities. It operates within a supply voltage range of 3 V to 12 V (or ±1.5 V to ±6 V dual supply). Key electrical parameters include a gain-bandwidth product of 1 MHz, a slew rate of 600 mV/us, and an input bias current of 10 pA. The device exhibits an input offset voltage of 750 uV and a common-mode rejection ratio of 90 dB. Each channel provides an output current of 10 mA with an operating supply current of 160 uA. It is housed in a TSSOP-14 package and functions reliably across a temperature range of -40°C to +85°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'G4' against the manufacturer's official documentation to confirm RoHS compliance status and lead time requirements. Ensure the TSSOP-14 package variant matches the design footprint. Cross-reference the datasheet revision date to validate parameter accuracy before finalizing procurement orders.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when designing single-supply applications requiring full input and output voltage swing near the rails. It is appropriate for general-purpose amplification where moderate bandwidth and low power consumption are prioritized over ultra-low noise or high-speed performance characteristics.
