Hello,
I was reading a note from texas Instruments about Charaterization of ADC. The note mentioned that a 12 bit ADC converter contains 244ppm / LSB. I want to know that how did they come up with this number? The note can be found at the following link
Regards, John
perhaps you could tell us what page are refering too?

Its page 207 or 12- 15.

Hi,
I have one more question that in chapter 4, the note disscuss how to design a opamp system using the four different combination of linear equation
Y = mX + B,
The author suggests the linear equation, defines the input and output voltages and then draws the circuit. My questions are
Thanks John
Is the other way around. He designed the circuits and check it with equations. But it sounds better to the professor than the schematic came from the equations.
How many ways can you build a house?
I didn't bother opening the link but....
2^12 = 4096 steps.LSB = 1/4096 = 244 e-6 =
244 ppm
1e6/2^12 = 244.
1 LSB = 1/4095 of full scale
1/4095 = 0.000244200244 = 244 ppm of full scale.

Fencepost error! Not that it matters muich, but the range of a 12-bit converter is 0 to 4095, and
1/4095 =3D> 244.200 parts per million of the range 1/4096 =3D> 244.141 parts per million
Which happens to be 4096 discrete values.
