PARAMETER
For the MAX1316/MAX1317/MAX1318, V
MAX1324/MAX1325/MAX1326, V
All channel performance is guaranteed by correlation to a single channel test.
Offset nulled.
The analog input resistance is terminated to an internal bias point. Calculate the analog input current using:
for V
Throughput rate is given per channel. Throughput rate is a function of clock frequency (f
