Description
16-Bit, 500ksps SAR ADC
with 94dB SNR
The LTC2392-16 is a low noise, high speed 16-bit suc-
cessive approximation register (SAR) ADC. Operating
from a single 5V supply, the LTC2392-16 supports a large
±4.096V fully differential input range, making it ideal for
high performance applications which require maximum
dynamic range. The LTC2392-16 achieves ±2LSB INL
max, no missing codes at 16-bits and 94dB SNR (typ).
The LTC2392-16 includes a precision internal reference
with a guaranteed 0.5% initial accuracy and a ±20ppm/°C
(max) temperature coefficient. Fast 500ksps throughput
with no cycle latency in both parallel and serial interface
modes makes the LTC2392-16 ideally suited for a wide
variety of high speed applications. An internal oscillator
sets the conversion time, easing external timing con-
siderations. The LTC2392-16 dissipates only 110mW at
500ksps,whilebothnapandsleeppower-downmodesare
provided to further reduce power during inactive periods.
