OPA380AIDGKR

Instrumentation, Op Amps, Buffer Amps Overview

The OPA380AIDGKR is a single-channel transimpedance amplifier from Texas Instruments, housed in an 8-VSSOP surface-mount package. It operates within a supply voltage range of 2.7 V to 5.5 V and supports an operating temperature range of -40°C to +125°C. Key electrical specifications include a gain-bandwidth product of 90 MHz, a slew rate of 80 V/µs, and a maximum output current of 150 mA per channel. The device features low input bias current (typically 3 pA), low input offset voltage (4 µV), and low input noise current density (10 fA). Supply current is typically 7.5 mA.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the complete part number including suffixes such as 'RG4' or specific tape-and-reel quantities when ordering. Confirm package type matches the design requirement, as variations exist between SOIC and VSSOP. Check manufacturer documentation for moisture sensitivity level and recommended soldering profiles to ensure reliable assembly during manufacturing processes.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when high bandwidth and low noise are critical for photodiode applications. Compare against the OPA381 if lower power consumption is prioritized over speed. Ensure the 150 mA output drive capability meets load requirements. Verify that the 8-VSSOP package fits the PCB layout constraints compared to larger packages like SOIC.

Instrumentation, Op Amps, Buffer Amps Part Context

The OPA380 belongs to the OPA380 family of precision transimpedance amplifiers designed for high-speed optical detection. It shares architectural similarities with the dual-channel OPA2380 but offers a single-channel configuration. This series targets applications requiring fast response times and high accuracy in converting small photocurrents into usable voltage signals.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

OPA2380AIDGKR is a dual-channel alternative within the same family. OPA381AIDGKR offers lower power consumption but reduced bandwidth.
