LT1468 Linear Technology, LT1468 Datasheet - Page 11

• Manufacturer Part Number: LT1468
• Description: 90MHz/ 22V/us 16-Bit Accurate Operational Amplifier
• Manufacturer: Linear Technology

APPLICATIONS
PACKAGE
Another key application for LT1468 is buffering the input
to a 16-bit A/D converter. In a gain of 1 or 2 this straight-
forward circuit provides uncorrupted AC and DC levels to
the converter, while buffering the A/D input sample-and-
