TYPICAL APPLICATION
 DESCRIPTION
16-Bit, 1Msps SAR ADC 
With 94dB SNR
The LTC
®
2393-16 is a low noise, high speed 16-bit suc-
cessive approximation register (SAR) ADC. Operating 
from a single 5V supply, the LTC2393-16 supports a large 
±4.096V fully differential input range, making it ideal for 
high performance applications which require maximum 
dynamic range. The LTC2393-16 achieves ±2LSB INL 
max, no missing codes at 16-bits and 94.2dB SNR (typ).
The LTC2393-16 includes a precision internal reference 
with a guaranteed 0.5% initial accuracy and a ±20ppm/°C 
(max) temperature coefficient. Fast 1Msps throughput with 
no cycle latency in both parallel and serial interface modes 
makes the LTC2393-16 ideally suited for a wide variety 
of high speed applications. An internal oscillator sets the 
conversion time, easing external timing considerations. 
The LTC2393-16 dissipates only 140mW at 1Msps, while 
both nap and sleep power-down modes are provided to 
further reduce power during inactive periods.
