TL972 (ACTIVE)

Output Rail-to-Rail Very-Low-Noise Operational Amplifier

 

Description

The TL97x family of single, dual, and quad operational amplifiers operates at voltages as low as ±1.35 V and features output rail-to-rail signal swing. The TL97x boast 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 preamplification.

The TL971 is housed in the space-saving 5-pin SOT-23 package, which simplifies board design because of the ability to be placed anywhere (outside dimensions are 2.8 mm × 2.9 mm).

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, 5 V/µs
  • Operating Range: 2.7 V to 12 V
  • Latch-Up Performance Exceeds 100 mA
    Per JESD 78, Class II
  • ESD Performance Tested Per JESD 22
    • 2000-V Human-Body Model
    • 1500-V Charged-Device Model
