LTC2335CLX-16#PBF

LTC2335CLX-16#PBF is a 16bit, low noise 8-channel multiplexed successive approximation register (SAR) ADC with differential, wide common mode range inputs. 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. The wide input common mode range and 118dB CMRR of the LTC2335-16 analogue inputs allow the ADC to directly digitize a variety of signals, simplifying signal chain design. This input signal flexibility, combined with ±1LSB INL, no missing codes at 16 bits, and 94.4dB SNR, makes the device an ideal choice for many high-voltage applications requiring wide dynamic range. Applications include programmable logic controllers, industrial process control, power line monitoring, test and measurement.
