Does the LTC2440 malfunction if it takes about 4-5ms to rise the power supply?
It sometimes can't be communicated.
I wanted to test out the performance of the LTC2440 Delta sigma ADC for a design that we are working on and had ordered the Demo board DC570A and the USB QuikEval demo board DC590B. I used the QuikEval program (http://ltspice.analog.com/software/ltcqev…
I like to know the possible configurations for LTC2440 to feed AC voltage with Zero DC offset.The AC voltage varies Vpp = 500mV to 1500mV. DC offset is almost zero(around -5mV).
I'm driving an LTC2440 24 bit sigma delta ADC with an AD8475 funnel amplifier. If I short the ADC inputs together I measure about 7 counts RMS noise, which is about 2uV RMS. This matches my expectation and the figures quoted on the ADC datasheet for a…
I'm interfacing a wheatstone bridge to a 24-bit ADC. The ADC is a LTC2440.
The output from the bridge is 0-50mV which I want to amplifie and modify to a 0-5v / 5-0v differential signal. Example bridige output and ADC input:mV +in. -in50…
Thank you for your comprehensive answer - just what I need to know. To be honest it was what I expected except for recently having looked at the LTC2400 and LTC2440 datasheets which show that their INL does vary with data-rate. That is presumably due…
