• Battery-Powered Instruments
The OPA333 (single version) is available in the 5-pin
• Handheld Test Equipment
SOT-23, SOT, and 8-pin SOIC packages, while the
OPA2333 (dual version) is available in the 8-pin
VSON, SOIC, and VSSOP packages. All versions are
specified for operation from –40°C to 125°C.
