FEATURES

DESCRIPTION

Simultaneous Sampling of 4 Buffered Channels

The LTC^®2357-18 is an 18-bit, low noise 4-channel

simultaneous sampling successive approximation regis-

ter (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, each channel of this

SoftSpan™ ADC can be independently configured on a

conversion-by-conversion basis to accept 10.24V, 0V to

10.24V, 5.12V, or 0V to 5.12V signals. Individual chan-

nels may also be disabled to increase throughput on the

remaining channels.

The integrated picoamp-input analog buffers, wide

input common mode range and 128dB CMRR of the

LTC2357-18 allow the ADC to directly digitize a variety

of signals using minimal board space and power. This

input signal flexibility, combined with 3.5LSB INL, no

missing codes at 18 bits, and 96.4dB SNR, makes the

LTC2357-18 an ideal choice for many high voltage appli-

cations requiring wide dynamic range.

APPLICATIONS

The LTC2357-18 supports pin-selectable SPI CMOS (1.8V

to 5V) and LVDS serial interfaces. Between one and four

lanes of data output may be employed in CMOS mode,

allowing the user to optimize bus width and throughput.
