Specifications of MAX1039AEEE

• Lead Free Status / Rohs Status: No

2.7V to 3.6V and 4.5V to 5.5V, Low-Power,
4-/12-Channel 2-Wire Serial 8-Bit ADCs
Table 4. Channel Selection in Pseudo-Differential Mode (SGL / DIF = 0)
Note 1: For MAX1036/MAX1037, CS3 and CS2 are internally set to zero.
Note 2: When SEL1 =1, a pseudo-differential read between AIN2 and AIN3/REF (MAX1036/MAX1037) or AIN10 and AIN11/REF
Note 3: When scanning multiple channels (SCAN0 = 0), CS0 = 0 causes the even-numbered channel-select bits to be scanned,

(MAX1038/MAX1039) returns the difference between GND and AIN2 or AIN10, respectively. For example, a pseudo-differen-
tial read of 1011 returns the negative difference between AIN10 and GND.
while CS0 = 1 causes the odd-numbered channel-select bits to be scanned. For example, if the MAX1038/MAX1039
SCAN[1:0] = 00 and CS[3:0] = 1010, a pseudo-differential read returns AIN0–AIN1, AIN2–AIN3, AIN4–AIN5, AIN6–AIN7,
AIN8–AIN9, and AIN10–AIN11. If the MAX1038/MAX1039 SCAN[1:0] = 00 and CS[3:0] = 1011, a pseudo-differential read
returns AIN1–AIN0, AIN3–AIN2, AIN5–AIN4, AIN7–AIN6, AIN9–AIN8, and AIN11–AIN10.
