OPA843IDBVT

Instrumentation, Op Amps, Buffer Amps Overview

The OPA843IDBVT is a single-channel, high-speed voltage feedback operational amplifier manufactured by Texas Instruments. It features an 800 MHz gain-bandwidth product and a 1 kV/us slew rate, housed in a compact SOT-23-5 surface-mount package. The device operates on a supply voltage range of 4 V to 6 V with a typical quiescent current of 20.2 mA per channel. Key electrical specifications include a low input voltage noise density of 2 nV/√Hz, a maximum open-loop voltage gain of 110 dB, and a common-mode rejection ratio of 95 dB. It supports output currents up to 100 mA and functions reliably within an industrial temperature range from -40°C to +85°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix IDBVT to confirm the SOT-23-5 package and tape-and-reel delivery format. Ensure compatibility with the required 4 V to 6 V supply rails and check moisture sensitivity levels for proper handling during assembly. Confirm that the operating temperature range meets the environmental requirements of the target application.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a balance of moderate bandwidth and low noise is required in a small form factor. It serves as a compact alternative to larger packages while maintaining high-speed performance. Consider the 20.2 mA quiescent current draw against power constraints and verify that the SOT-23-5 thermal dissipation capabilities are sufficient for the intended load conditions.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the OPA843 series of wideband, low-distortion voltage feedback amplifiers. It shares core electrical characteristics with other variants in the family but is distinguished by its specific SOT-23-5 packaging and reel-based distribution method. The series is designed for applications requiring high speed and precision in space-constrained designs.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The OPA843IDG4 is a pin-compatible alternative available in an SOIC-8 tube package. Verify that the change in physical dimensions and thermal properties does not impact the existing printed circuit board layout or heat dissipation strategy.
