Description

OPA387DBVR is a Texas Instruments precision op-amp. It belongs to the OPA387 family and is offered in an 8-pin VSSOP package (DBVR is the RoHS, tape‑and‑reel version of the DBV/VSSOP package).
Key points:
- Rail-to-rail input and output
- Low offset, low bias current, and low noise for high-precision amplification
- Wide single-/dual-supply operating range (check datasheet for exact voltages)
- Suitable for DAC buffering, sensor signal conditioning, transimpedance stages, instrumentation, and precision amplification
Packaging and usage:
- Package: VSSOP-8 (DBVR)
- Requires proper power supply decoupling and attention to input common-mode range and output swing in your circuit
- Refer to the datasheet for exact electrical specs (GBW, slew rate, input offset, noise) and recommended closed-loop configurations
For detailed specs and pinout, consult the TI OPA387 datasheet.

Features

Key features of OPA387DBVR (TI):
- Precision, low-noise operational amplifier
- Single-supply and dual-supply operation
- Rail-to-rail input and output
- Very low input offset voltage and low offset drift
- Very low input bias current
- Low input-referred voltage noise
- Moderate to high gain-bandwidth and fast slew rate for dynamic signals
- Unity-gain stability
