Микросхемы и комплектующие LTC2333ILX-16#PBF

АЦП , 16 бит, 800 Квыборок/с, Дифференциальный, SPI, Однополярный, 4.75 В

The LTC2333ILX-16#PBF from Linear Technology is a buffered 8-channel, 16bit, 800Ksps differential ±10.24V ADC with 30VP-P common mode range in 48 pin LQFP package. It is a low noise 8-channel multiplexed successive approximation register (SAR) ADC with buffered differential, differential wide common mode range picoamp inputs. Operating from a 5V low voltage supply, flexible high voltage supplies and using 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 integrated picoamp input analogue buffers, wide input common mode range and 128dB CMRR of the LTC2333-16 allow the ADC to directly digitize a variety of signals using minimal board space and power. This input signal flexibility, combined with ±1LSB INL, no missing codes at 16bit and 94.2dB SNR, makes the LTC2333-16 an ideal choice for many high voltage applications requiring wide dynamic range.
