TS321 (ACTIVE)

Low-Power Single Operational Amplifier

 

Description

The TS321 is a bipolar operational amplifier for cost-sensitive applications in which space savings are important.

Features

  • Wide Power-Supply Range
    • Single Supply from 3 V to 30 V
    • Dual Supply from ±1.5 V to ±15 V
  • Large Output Voltage Swing from 0 V to 3.5 V (Minimum) (VCC = 5 V)
  • Low Supply Current at 500 µA (Typical)
  • Low Input Bias Current at 20 nA (Typical)
  • Stable With High Capacitive Loads
