OPA656 Description

Short technical summary and product information.

The OPA656 from Texas Instruments is a high-performance, voltage-feedback operational amplifier featuring a JFET input stage. This design provides an ultra-high dynamic range suitable for transimpedance applications and high-speed data acquisition systems.

Key electrical characteristics include a wide bandwidth with a gain-bandwidth product of 230MHz and a unity-gain bandwidth of 550MHz. It also boasts a large-signal bandwidth of 150MHz at 2VPP. The amplifier offers high precision with a maximum input offset voltage of 600μV and a drift of 6μV/°C. Noise performance is excellent, with an input voltage noise of 6nV/√Hz and low input bias current of 2pA.

Distortion figures are impressive, with HD2 and HD3 at 5MHz measuring -80dBc and -100dBc respectively, under specific load conditions. The device operates from a supply voltage range of 8V to 12V and is specified for an industrial temperature range of -40°C to +85°C.

The OPA656 is available in SOIC (8-pin) and SOT-23 (5-pin) packages. The SOIC package measures 4.9mm x 6mm, while the SOT-23 package measures 2.9mm x 2.8mm. Its characteristics make it suitable for applications such as high-speed data acquisition, active probes, oscilloscopes, and optical communication modules.
