FEATURES

DESCRIPTION

TheLTC^®2353-16isa16-bit, lownoise2-channelsimulta-

neous sampling successive approximation register (SAR)

ADC with buffered differential, wide common mode range

picoamp inputs. Operating from a 5V low voltage sup-

ply, flexible high voltage supplies, and using the internal

reference and buffer, both channels of this SoftSpan^TM

ADC can be independently configured on a conversion-

by-conversion basis to accept 1ꢀ.2ꢁV, ꢀV to 1ꢀ.2ꢁV,

5.12V, or ꢀV to 5.12V signals. One channel may also

be disabled to increase throughput on the other channel.

Iꢀ

The integrated picoamp-input analog buffers, wide input

commonmoderangeand12ꢁdB CMRRoftheLTC2353-16

allow the ADC to directly digitize a variety of signals us-

ing minimal board space and power. This input signal

flexibility, combined with 1LSB INL, no missing codes

at 16 bits, and 9ꢁ.2dB SNR, makes the LTC2353-16 an

ideal choice for many high voltage applications requiring

wide dynamic range.

ꢁ8-Lead (7mm x 7mm) LQFP Package

TheLTC2353-16supportspin-selectableSPICMOS(1.8V

to 5V) and LVDS serial interfaces. Either one or two lanes

of data output may be employed in CMOS mode, allowing

the user to optimize bus width and throughput.
