2.5V Supply  
The LTC2380-16 has a high speed SPI-compatible serial  
interface that supports 1.8V, 2.5V, 3.3V and 5V logic  
while also featuring a daisy-chain mode. The fast 2Msps  
throughput with no cycle latency makes the LTC2380-16  
ideally suited for a wide variety of high speed applications.
