Product Overview

The LTC6419IV#PBF from Linear Technology is a dual, 10GHz GBW, 1.1nV/√Hz differential amplifier/ADC driver in 20 pin LGA package. This is a very high speed, low distortion differential amplifier. Its input common mode range includes ground, so that a ground referenced single ended or differential input signal can be DC coupled, level shifted and converted to drive an ADC differentially. The gain and feedback resistors are external, so that the exact gain and frequency response can be tailored to each application. The LTC6419 is stable in a differential gain of 1. This allows for low output noise in applications where gain is not desired. Each amplifier draws 52mA of supply current and has an independent shutdown pin which reduces current consumption to 100µA per amplifier. It is used in broadband I/Q amplifier, dual differential ADC driver, high speed data acquisition cards, automated test equipment, time domain reflectometry & communications receivers.
  • 85dB SFDR at 100MHz (2VP-P), 1.1nV/√Hz input noise density, fully differential input and output
  • Channel separation of 95dB at f = 100MHz, input offset current of ±2µA at VS = 3V
  • Supply voltage range from 2.7V to 5.25V, external resistors set gain (1V/V minimum)
  • 3300V/µs differential slew rate, 1.4GHz -3dB frequency and 1.9ns settling time
  • Output common mode rejection ratio of 80dB at VS = 3V, VOCM from 0.5V to 1.5V
  • Output common mode power supply rejection of 70dB at VS = 2.7V to 5.25V
  • Differential offset voltage (input referred) of ±300µV, input bias current of -62µA (VS = 3V)
  • Supply current (per amplifier) of 52mA and supply current (per amplifier) of 100µA in shutdown mode
  • Adjustable output common mode voltage low power shutdown
  • Operating temperature range from -40°C to 85°C
