LTC2345HUK-16#PBF

LINEAR TECHNOLOGY  LTC2345HUK-16#PBF  Analogue to Digital Converter, SoftSpan, Octal, 16 bit, 200 kSPS, Single, 4.75 V, 5.25 V, QFN 新

The is an octal, 16bit, 200Ksps differential SoftSpan ADC with wide input common mode range in 48 pin QFN package. This 16bit, low noise 8-channel simultaneous sampling successive approximation register SAR ADC with differential, wide common mode range inputs. It operating from a 5V low voltage supply 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 ±4.096, 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. The IC"s analogue inputs allow ADC to directly digitize a variety of signals, simplifying signal chain design. It is used in programmable logic controllers, industrial process control and high speed data acquisition.
