Product overview

Description

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.

  • All features

    • Submicro ampere current consumption: 580 nA typ 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: 2 pA max at 25 °C
    • Industrial temperature range: -40 °C to 85 °C
    • Benefits:
      • 42 years of typical equivalent lifetime supplied by a 220 mA.h coin-type Lithium battery
      • Tolerance to power supply transient drops
      • Accurate signal conditioning of high impedance sensors
