TS971, TS972, TS974 Output rail-to-rail very low noise operational amplifier Datasheet - production data Features Rail-to-rail output voltage swing ±2.4 V at V = ±2.5 V CC Very low noise level: 4 nV/√Hz Ultra low distortion: 0.003 % High dynamic features: 12 MHz, 4 V/µs Operating range: 2.7 to 10 V ESD protection (2 kV) Latch-up immunity (class A) Applications Portable devices (CD players, PDAs) Portable communication (cell phones, pagers) Instrumentation and sensing technology Professional audio circuits Description The TS97x family of operational amplifiers operate with voltages as low as ±1.35 V and feature output rail-to-rail signal swing. The TS97x devices are particularly well suited for portable and battery-supplied equipment. Very low noise and low distortion characteristics make them ideal for audio pre-amplification. The TS97x devices are available in a variety of packages to suit all types of applications. For applications where space saving is critical, the SOT23-5 package (2.8 x 2.9 mm) or the DFN8 package (3 x 3 mm) simplify the board design because they can be placed anywhere on it.

(2)The differential voltage is the non-inverting input terminal with respect to the inverting input terminal. (3)The magnitude of input and output voltages must never exceed VCC + 0.3 V. (4)Short-circuits can cause excessive heating and destructive dissipation. Values are typical. (5)Human body model: a 100 pF capacitor is charged to the specified voltage, then discharged through a 1.5kΩ resistor between two pins of the device. This is done for all couples of connected pin combinations while the other pins are floating. (6)Machine model: a 200 pF capacitor is charged to the specified voltage, then discharged directly between two pins of the device with no external series resistor (internal resistor < 5 Ω). This is done for all couples of connected pin combinations while the other pins are floating. (7) No value specified for CDM on SOT23-5 package. (8)Charged device model: all pins and package are charged together to the specified voltage and then discharged directly to ground through only one pin. This is done for all pins. 4/18 DocID6031 Rev 11
