The TS97x boasts characteristics that make them particularly well suited for portable and battery-supplied equipment. Very low noise and low distortion characteristics make them ideal for audio pre-amplification. The TS971 is housed in the space-saving 5 pins SOT23 package which simplifies the board design because of the ability to be placed everywhere (outside dimensions are 2.8mm x 2.9mm) N.C. 8 N.C. 1 Inverting Input 1 2 - 7 VCC 3 + 6 Ou tpu t 2 Non-inve rting Input 1 5 N.C.
