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.
