Driver for 14-Bit, 4.5Msps ADC Operates Over a Wide Gain Range

Guy Hoover - Applications Engineer Apr 3rd 2014
Introduction The LTC2314-14 is a 14-bit, 4.5Msps, serial output ADC with an integrated high performance reference. The single-ended input of the LTC2314-14 is easy to drive and in many instances does not require a buffer. A driver, such as the LT6236 op amp, may be required for a signal that is small or has high output impedance. ...

ADC Drivers & Filters: Single Ended Buffer

Guy Hoover - Applications Engineer Aug 28th 2013
Figure 1 shows a recommended single ended buffered drive circuit using the LT1818 in unity gain mode. The 47pF capacitor from AIN to ground and 50Ω source resistor limits the input bandwidth to 68MHz. The 47pF capacitor also acts as a charge reservoir for the input sample-and-hold and isolates the LT1818 from sampling ...
