OPA2835ID

Instrumentation, Op Amps, Buffer Amps Overview

The OPA2835ID is a dual ultra-low power voltage feedback operational amplifier manufactured by Texas Instruments. It features a gain-bandwidth product of 30 MHz and a slew rate of 160 V/us. The device operates within a supply voltage range of 2.5 V to 5.5 V, consuming only 250 uA per channel. Key electrical specifications include an input offset voltage of 100 uV, input bias current of 400 nA, and output current capability of 40 mA per channel. It offers rail-to-rail input and output capabilities with a voltage noise density of 25 nV/sqrt Hz. The component is housed in an 8-SOIC package and supports operating temperatures from -40 C to +125 C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'ID' corresponds to the SOIC-8 package and industrial temperature range (-40°C to +125°C). Confirm moisture sensitivity level (MSL) requirements for surface mount assembly processes. Ensure compatibility with standard 8-pin SOIC footprints during PCB layout design. Cross-reference datasheet revisions for any updates to electrical characteristics or recommended operating conditions.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when low quiescent current is critical alongside moderate speed requirements. The rail-to-rail I/O feature simplifies single-supply designs compared to traditional amplifiers. Consider the 8-SOIC package constraints for thermal management if multiple units are placed closely. Compare against higher bandwidth options if signal fidelity at frequencies above 30 MHz is required.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the OPA2835 series of high-speed operational amplifiers designed for low-power applications. It shares core performance metrics with other variants like the OPA2835IDR but differs in packaging and shipping configuration. The series emphasizes efficiency without sacrificing significant speed, targeting modern portable electronics where power budget is strictly limited.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

OPA2835IDR: Same electrical specifications and functionality; differs only in tape-and-reel packaging instead of bulk tube.
