OPA653IDBVT

Instrumentation, Op Amps, Buffer Amps Overview

The OPA653IDBVT is a single-channel, high-speed voltage feedback operational amplifier manufactured by Texas Instruments. It features a JFET input stage and a fixed internal gain of +2 V/V. Key electrical parameters include a bandwidth of 500 MHz, a slew rate of 2.675 kV/µs, and an output current capability of 70 mA. The device operates within a supply voltage range of 3.5 V to 6.5 V, drawing 32 mA of quiescent current. Input specifications include a bias current of 50 pA, offset voltage of 1 mV, and noise density of 6.1 nV/√Hz. It is housed in a compact SOT-23-5 surface-mount package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the complete part number including the IDBVT suffix to ensure correct package type and tape-and-reel configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Check moisture sensitivity levels and reflow soldering profiles to prevent damage during assembly. Ensure the selected variant matches the required fixed-gain specification rather than variable-gain alternatives.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a fixed gain of +2 V/V is required without external feedback resistors. Consider the SOT-23-5 package constraints for thermal management and PCB space. Evaluate the 500 MHz bandwidth against system frequency requirements. Compare input bias current and noise specifications with other JFET-input amplifiers if ultra-low noise or higher precision is needed.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the OPA653 series of high-speed operational amplifiers from Texas Instruments. It is designed specifically for applications requiring fixed gain configurations to reduce board space and component complexity. The series targets video and RF markets where signal integrity and speed are critical.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Check for updated revisions of the OPA653 family. Verify pin compatibility if substituting with other fixed-gain amplifiers. Ensure bandwidth and slew rate meet or exceed original requirements.
