Nanopower 5V CMOS op-amp

The TSU101, TSU102, and TSU104 operational amplifiers offer an ultra low-power consumption of 580 nA typical and 750 nA maximum per channel when supplied by 1.8 V. Combined with a supply voltage range of 1.5 V to 5.5 V, these features allow the TSU10x series to be efficiently supplied by a coin type Lithium battery or a regulated voltage in low-power applications.

The 8 kHz gain bandwidth of these devices make them ideal for sensor signal conditioning, battery supplied, and portable applications.

Key Features

  • Submicro ampere current consumption: 580 nA typ per channel at 25 °C at VCC = 1.8 V
  • Low supply voltage: 1.5 V - 5.5 V
  • Unity gain stable
  • Rail-to-rail input and output
  • Gain bandwidth product: 8 kHz typ
  • Low input bias current: 5 pA max at 25 °C
  • High tolerance to ESD: 2 kV HBM
  • Industrial temperature range: -40 °C to 85 °C
    • 42 years of typical equivalent lifetime (for TSU101) if supplied by a 220 mAh coin type Lithium battery
    • Tolerance to power supply transient drops
    • Accurate signal conditioning of high impedance sensors
    • Application performances guaranteed over industrial temperature range
    • Fast desaturation
