Texas Instruments Inc. (TI) introduced a 4-by-4mm DFN package version of the high-precision OPA277 operational amplifier (op amp) from its burr-brown product line. This leadless, near-chip-scale package is less than 1mm thick and features contacts on only two sides, minimizing board space requirements and enhancing thermal characteristics through an exposed pad. The DFN package can easily be mounted using standard PCB assembly techniques, added TI.

The OPA277's reduced package size allows compact designs in a variety of applications, including industrial electronics, temperature measurement, battery-powered instruments and test equipment, and helps preserve precision by keeping the chip temperature low as the power is easily dissipated through the exposed pad. Additionally, the OPA277 features ultra low offset voltage (35?V typical) and drift, low bias current, high common-mode rejection and higher power supply rejection. The device also offers high open-loop gain and a wide supply range (to 18V).

The OPA277 (single) and OPA2277 (dual) are available in 4-by-4mm DFN packages. The single and dual versions have a suggested resale pricing of 85 cents and $1.65, respectively in 1,000-piece quantities.
