ADI’s OP275 combines both bipolar and JFET transistors for amplification and accuracy in an audio op amp. This amp has wide bandwidth of 9 MHz, low supply current of 5 mA, and stable unit gain.  This device comes in either a dual- 8-pin DIP or SOIC package with a temperature range of -40°C to +85°C. The OP275 is ideal for audio DC coupled or summing applications that require low power and precision.
