The LTC®6419 is a dual 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. For example, the amplifier could be externally compensated in a no-overshoot configuration, which is desired in certain time-domain applications.
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.
The LTC6419 is available in a compact 4mm × 3mm 20‑pin LGA package and operates over a –40°C to 125°C temperature range.
