LTC2333-18
Buffered 8-Channel, 18-Bit, 800ksps
Differential ±10.24V ADC with
30V
P-P
Common Mode Range
DESCRIPTION
The
LTC
®
2333-18
is an 18-bit, low noise 8-channel multi-
plexed successive approximation register (SAR) ADC with
buffered differential, wide common mode range picoamp
inputs. Operating from a 5V low voltage supply, flexible
high voltage supplies, and using the internal reference
and buffer, this SoftSpan™ ADC can be configured on a
conversion-by-conversion basis to accept ±10.24V, 0V to
10.24V, ±5.12V, or 0V to 5.12V signals on any channel.
Alternately, the ADC may be programmed to cycle through
a sequence of channels and ranges without further user
intervention.
The integrated picoamp-input analog buffers, wide input
common mode range and 128dB CMRR of the LTC2333-
18 allow the ADC to directly digitize a variety of signals
using minimal board space and power. This input signal
flexibility, combined with ±3LSB INL, no missing codes
at 18 bits, and 96.4dB SNR, makes the LTC2333-18 an
ideal choice for many high voltage applications requiring
wide dynamic range.
The LTC2333-18 supports pin-selectable SPI CMOS (1.8V
to 5V) and LVDS serial interfaces.
