MAX1304–MAX1306/MAX1308–MAX1310/MAX1312–MAX1314
8-/4-/2-Channel, 12-Bit, Simultaneous-Sampling ADCs
with ±10V, ±5V, and 0 to +5V Analog Input Ranges

_______________________________________________________________________________________
Note 1: For the MAX1304/MAX1305/MAX1306, VIN = 0 to +5V. For the MAX1308/MAX1309/MAX1310, VIN = -5V to +5V. For the
MAX1312/MAX1313/MAX1314, VIN = -10V to +10V.
Note 2: All channel performance is guaranteed by correlation to a single channel test.
Note 3: The analog input resistance is terminated to an internal bias point (Figure 5). Calculate the analog input current using:
for VCH_ within the input voltage range.
Note 4: Throughput rate is given per channel. Throughput rate is a function of clock frequency (fCLK). The external clock through-
put rate is specified with fCLK = 16.67MHz and the internal clock throughput rate is specified with fCLK = 15MHz. See the
Data Throughput section for more information.
Note 5: The REF input resistance is terminated to an internal +2.5V bias point (Figure 2). Calculate the REF input current using:
for VREF within the input voltage range.
Note 6: The REFMS input resistance is terminated to an internal +2.5V bias point (Figure 2). Calculate the REFMS input current using:
for VREFMS within the input voltage range.
Note 7: All analog inputs are driven with a -0.4dBFS 500kHz sine wave.
Note 8: Shutdown current is measured with the analog input unconnected. The large amplitude of the maximum shutdown current
specification is due to automated test equipment limitations.
Note 9: CONVST must remain low for at least the acquisition period. The maximum acquisition time is limited by internal capacitor droop.
Note 10: CS to WR and CS to RD are internally AND together. Setup and hold times do not apply.
Note 11: Minimum CLK frequency is limited only by the internal T/H droop rate. Limit the time between the rising edge of CONVST
and the falling edge of EOLC to a maximum of 1ms.
