LT1994
Low Noise, Low Distortion
Fully Differential Input/
Output Amplifier/Driver
FEATURES DESCRIPTION n The LT®1994 is a high precision, very low noise, low distortion, fully differential input/output amplifier optimized for
3V, single-supply operation. The LT1994’s output common
mode voltage is independent of the input common mode
voltage, and is adjustable by applying a voltage on the
VOCM pin. A separate internal common mode feedback
path provides accurate output phase balancing and reduced
even-order harmonics. This makes the LT1994 ideal for
level shifting ground referenced signals for driving differential input, single-supply ADCs. n Fully Differential Input and Output
