OPA561PWP/2K

Instrumentation, Op Amps, Buffer Amps Overview

The OPA561PWP/2K is a high-current, high-speed operational amplifier manufactured by Texas Instruments. It delivers up to 1.2A output current and supports a supply voltage range of 7V to 15V (single) or ±3.5V to ±7.5V (dual). Key electrical parameters include a 17MHz gain-bandwidth product, 50V/µs slew rate, and 1MHz full-power bandwidth. The device features adjustable current limiting from 0.2A to 1.2A, thermal shutdown protection, and an enable/status pin. It operates within an extended temperature range of -40°C to +125°C and is housed in a thermally enhanced HTSSOP-20 PowerPAD package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix /2K corresponds to the tape and reel packaging quantity of 2000 units as documented in the manufacturer's ordering information. Confirm that the HTSSOP-20 PowerPAD package requires direct soldering of the thermal pad to the PCB ground plane for proper thermal performance. Ensure design compatibility with the specified single or dual supply voltage ranges before procurement.
