Note 1:
For the MAX1316/MAX1317/MAX1318, VIN = 0 to +5V. For the MAX1320/MAX1321/MAX1322, VIN = -5V to +5V. For the
MAX1324/MAX1325/MAX1326, VIN = -10V to +10V.
Note 2:
All channel performance is guaranteed by correlation to a single channel test.
Note 3:
Offset nulled.
Note 4:
The analog input resistance is terminated to an internal bias point. Calculate the analog input current using:
for VCH within the input voltage range.
Note 5:
Throughput rate is given per channel. Throughput rate is a function of clock frequency (fCLK = 10MHz). See the Data
Throughput section for more information.
Note 6:
All analog inputs are driven with an FS 100kHz sine wave.
