The ISL55210 is a very wide band, Fully Differential Amplifier (FDA) intended for high dynamic range ADC input interface applications. This voltage feedback FDA design includes an independent output common mode voltage control. Intended for very high dynamic range ADC interface applications, at the lowest quiescent power (115mW), the ISL55210 offers a 4. 0GHz Gain Bandwidth Product with a very low input noise of 0. 85nV/√(Hz). In a balanced differential I/O configuration, with 2VP-P output into a 200Ω load configured for a gain of 15dB, the IM3 terms are


  • Gain Bandwidth Product: 4.0GHz
  • Input Voltage Noise: 0.85nV/√(Hz)
  • Differential Slew Rate: 5,600V/µs
  • 2VP-P, 2-tone IM3 (200Ω) 100MHz: -109dBc
  • Supply Voltage Range: 3.0V to 4.2V
  • Quiescent Power (3.3V Supply): 115mW


  • Low Power, High Dynamic Range ADC Interface
  • Differential Mixer Output Amplifier
  • SAW Filter Pre/Post Driver
  • Differential Comms-DAC Output Driver
