LTC2391-16  
16-Bit, 250ksps SAR ADC  
with 94dB SNR  
FEATURES  
DESCRIPTION  
The LTC®2391-16 is a low noise, high speed 16-bit suc-  
cessive approximation register (SAR) ADC. Operating  
from a single 5V supply, the LTC2391-16 supports a large  
±±.ꢀ96V fully differential input range, maꢁing it ideal for  
high performance applications which require maximum  
dynamic range. The LTC2391-16 achieves ±2LSꢂ ꢃIL  
max, no missing codes at 16-bits and 9±dꢂ SIR (typ).

The LTC2391-16 includes a precision internal reference  
with a guaranteed ꢀ.5% initial accuracy and a ±2ꢀppmꢄ/C  
(max) temperature coefficient. Fast 25ꢀꢁsps throughput  
with no cycle latency in both parallel and serial interface  
modes maꢁes the LTC2391-16 ideally suited for a wide  
variety of high speed applications. An internal oscillator  
sets the conversion time, easing external timing con-  
siderations. The LTC2391-16 dissipates only 95mW at  
25ꢀꢁsps,whilebothnapandsleeppower-downmodesare  
provided to further reduce power during inactive periods.
