TS971:Output rail-to-rail very low-noise op-amps

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.

Key Features

  • Rail-to-rail output voltage swing ±2.4 V at VCC = ±2.5 V
  • 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)
