ADS1110: Data conversion volts per tick

Glenn Varnon52

Part Number: ADS1110

Currently I am using the ADS1110 with a gain of 1 and as a 16 bit A/D.

So as I understand it, the differential voltage maximum would be +/-2048/1. To figure out the volts per tick would you go 4096/65535 = 0.0625 volts per tick?

Hello,

You've pretty much got it correct, but the denominator should be 2^n which is 65536 for a 16-bit converter. The general formula is LSB(Volts) = VFSR/ (2^n). Where VFRS is the full-scale voltage (+/-2.048V = 4.096V) and n is the number of bits. 2^16 = 65536. 4.096V / (65536) = 0.0625V
