AD7705 Dual 16 bit ADC Module with Programmable Input Gain and SPI Interface TM7705

:COM07017
€3.21

The AD7705 is analog-to-digital converters (ADC)
with on-chip digital filtering, intended for the measurement of
wide, dynamic range, low frequency signals, such as those in
industrial-control or process-control applications. Each contains
a (or charge-balancing) ADC, a calibration microcontroller
with on-chip static RAM, a clock oscillator, a digital filter, and a
bidirectional serial communication port.
