OPA683IDBVR

Instrumentation, Op Amps, Buffer Amps Overview

The OPA683IDBVR is a single-channel, very-low-power, wideband current-feedback amplifier manufactured by Texas Instruments. It operates within a supply voltage range of 5 V to 12 V and draws only 1.7 mA of quiescent current. The device features a high slew rate of 820 V/µs and a gain-bandwidth product of 200 MHz. Key electrical specifications include an input offset voltage of 3.5 mV, input bias current of 10 µA, and input voltage noise density of 3.7 nV/√Hz. It provides a common-mode rejection ratio (CMRR) of 53 dB to 60 dB and a power supply rejection ratio (PSRR) of 65 dB. The component is housed in a compact SOT-23-6 surface-mount package and is rated for operation between -40°C and +85°C.

• High-speed data acquisition systems
• RF and IF amplification stages

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'DBVR' corresponds to the SOT-23-6 package and tape-and-reel shipping format as indicated by distributor listings. Confirm RoHS compliance status through the manufacturer's official documentation prior to integration. Ensure design compatibility with the specified 5 V to 12 V supply range and thermal requirements for the SMD/SMT installation style.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when high slew rate and wide bandwidth are required alongside strict power consumption limits. The current-feedback architecture is preferred over voltage-feedback types for applications demanding consistent bandwidth regardless of closed-loop gain. Consider the SOT-23-6 package constraints for PCB layout and thermal dissipation relative to the 1.7 mA operating current.

Instrumentation, Op Amps, Buffer Amps Part Context

The OPA683 belongs to Texas Instruments' OPA68x family of current-feedback amplifiers, designed to offer enhanced performance in very low-power, wideband applications. This series introduces CFBplus technology to improve stability and speed. The OPA683IDBVR represents the single-channel variant in a small outline transistor package, distinguishing it from dual-channel or larger package options within the same functional family.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The OPA684IDBVR is a documented alternative within the same series offering similar current-feedback characteristics. Verify pinout compatibility and specific parameter differences such as slew rate and noise before substitution.
