The OP290GSZ is typically available in a SOIC (Small Outline Integrated Circuit) package. Key specifications include a low supply current and a wide input common-mode voltage range that includes ground. The operating temperature range is generally specified for industrial applications (-40°C to +85°C). Single-supply operation is particularly advantageous in systems where generating a negative supply rail is impractical or costly. Its low power consumption and single-supply capability make it an excellent choice for portable and battery-operated devices where long operating life and efficient power management are essential.
