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) 1 Inverting Input 1 2 - 7 VCC Non-inverting Input 1 3 + 6 Ou tput 2 TS972IN-TS972ID-TS972IDT-TS972IPT ers) ■ Instrumentation & sensoring ■ Professional audio circuits 1 2 - Non-inve rting Input 1 3 + VDD 4 -40°C, +125°C 6 Inverting Input 2 + 5 Non-inve rting Input 2 1 8 VCC Inverting Input 1 2 7 Output 2 Non Inverting Input 1 3 6 Inverting Input 2 4 5 Non Inverting Input 2 TS974IN-TS974ID-TS974IDT-TS974IPT Package N D P • L Q • TS972I -40°C, +125°C • • • TS974I -40°C, +125°C • • • SOT23 Marking Output 1 1 K120 • N = Dual in Line Package (DIP) D = Small Outline Package (SO) - also available in Tape & Reel (DT) P = Thin Shrink Small Outline Package (TSSOP) - only available In Tape & Reel (PT) L = Tiny Package (SOT23-5) - only available in Tape & Reel (LT) Q = QFN only available in Tape & Reel with T suffix, November 2002 7 Output 2 - Output 1 VDD ORDER CODE TS971I 8 VCC Output 1 Inverting Input 1 TS972IQT : QFN8 ■ Portable equipments (CD players, PDA) ■ Portable communications (cell phones, pag- Temperature Range 5 N.C.
