FEATURES  
DESCRIPTION  
The LTC®2368-16 is a low noise, low power, high speed  
16-bit successive approximation register (SAR) ADC.

2.5V Supply  
The LTC2368-16 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 LTC2368-16  
ideally suited for a wide variety of high speed applications.

nal timing considerations. The LTC2368-16 automatically  
powers down between conversions, leading to reduced  
power dissipation that scales with the sampling rate.
