Differential amplifier for data-acquisition front ends
The Analog Devices LTC6419HV#PBF is a differential op-amp with two circuits in a single 20-LQFN (4x3) package. It is designed for data-acquisition signal chains where a differential interface to an ADC or a balanced line receiver is needed.
Package and thermal: 20-VFQFN Exposed Pad
Surface-mount assembly is standard; the pad pitch and dimensions match the LQFN-20 footprint common across this family.
For BOM planning, this is a low-risk line item with no imminent obsolescence concern.
