LTC2344-16
Quad, 16-Bit, 400ksps/ch
Differential SoftSpan ADC with
Wide Input Common Mode Range
DESCRIPTION FEATURES The LTC®2344-16 is a 16-bit, low noise 4-channel simultaneous sampling successive approximation register (SAR)
ADC with differential, wide common mode range inputs.
Operating from a 5V supply and using the internal reference
and buffer, each channel of this SoftSpanTM ADC can be
independently configured on a conversion-by-conversion
basis to accept ±4.096V, 0V to 4.096V, ±2.048V, or 0V to
2.048V signals. Individual channels may also be disabled
to increase throughput on the remaining channels. 400ksps per Channel Throughput
