For the MAX1316/MAX1317/MAX1318, V_IN = 0 to +5V. For the MAX1320/MAX1321/MAX1322, V_IN = -5V to +5V. For the
MAX1324/MAX1325/MAX1326, V_IN = -10V to +10V.
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:
I_{CH_}
=
V_{CH_} − V_BIAS
R_{CH_}
for V_CH within the input voltage range.
Note 5: Throughput rate is given per channel. Throughput rate is a function of clock frequency (f_CLK = 10MHz). See the Data
Throughput section for more information.
Note 6: All analog inputs are driven with an FS 100kHz sine wave.
