Texas Instruments OPA860ID Operational Transconductance Amplifier in SOIC-8 Package

The Texas Instruments OPA860ID in an SOIC-8 package is an operational transconductance amplifier (OTA) designed for voltage-to-current conversion in analog signal processing. This linear integrated circuit offers controlled transconductance behavior suitable for filter stages, modulators and sensor interfaces where a compact IC package and predictable current output are required.

Advantages

The OPA860ID provides stable transconductance characteristics and low distortion across its operating range, enabling consistent analog performance. Its SOIC-8 form factor simplifies PCB layout and thermal management in compact designs. The device's linear response and predictable current output make it suitable for precision signal conditioning and active network implementations.

Key specifications

• Function: operational transconductance amplifier (voltage-to-current conversion)
• Package type: SOIC-8 (small-outline integrated circuit, 8 leads)
• Operational behavior: linear transconductance with low distortion
• Intended use: analog signal processing, filters, modulators, sensor interfaces

How to use

Integrate the OPA860ID into the circuit following standard OTA design practices: provide appropriate power-supply rails, biasing and input protection as required by the surrounding circuitry. Connect input voltage to the amplifier input pins and take the resulting output as a current from the designated output terminal, routing that current into the subsequent stage or to a transimpedance element if a voltage output is needed. Observe manufacturer recommendations for supply decoupling and layout to maintain transconductance stability and minimize noise.

Recommendations

Use short traces for inputs and outputs and place bypass capacitors close to supply pins to reduce interference. When converting the OTA output current to a voltage, select a transimpedance resistor or amplifier stage with suitable bandwidth and noise performance for the intended application.
