LTC2335CLX-18#PBF

LINEAR TECHNOLOGY  LTC2335CLX-18#PBF  模数转换器, 8通道, 18 bit, 1 MSPS, 单, 4.75 V, 5.25 V, LQFP 新

The is a 18bit, 1Msps 8-channel differential ±10.24V input SoftSpan ADC with wide input common mode range in 48 pin LQFP package. This is multiplexed successive approximation register SAR ADC with differential, wide common mode range inputs. It 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 analogue inputs allow the ADC to directly digitize a variety of signals, simplifying signal chain design. It is used in programmable logic controllers, power line monitoring and industrial process control.
