Can You Use the Voltage Reference to Power Your ADC Driver?
Jul 11th 2013
Linear Technology’s family of 16-, 18-, and 20-Bit SAR ADCs (LTC2378-20 family) operates with an external reference voltage of up to 5V. The largest input voltage that you are then supposed to put on each ADC input pin is equal to that 5V reference voltage. It seems logical to use an opamp on a 5V supply with rail-to-rail ...

Debugging the LTC6946: Getting the PLL to Lock
Mar 21st 2013
The DC1705 and the PLLWizard software provide a complete evaluation system for the LTC6946 that makes it easy to determine how the part will behave in your system. However, a common problem can occur when designing any PLL system - what if the PLL is not locking to the proper frequency? In cases where the LTC6946 RF output ...
