U1, the MAX1110, is an 8-channel, 8-bit, low-power
analog-to-digital converter (ADC) with serial interface
and a shutdown mode. R1–R8 and C1–C8 act as anti-
aliasing input filters. V

information.
C9 and C11 are 4.7µF bypass capacitors for the refer-
ence and the power supply. For reduced board size

Use the internal reference (REFIN is
connected to REFOUT).
Analog common voltage must be set
by user.
Analog common (COM) = GND.

and/or lower cost, C9 and C11 may be reduced to 1µF.
R9 and C10 filter the digital noise out of the analog
power supply.
The EV kit has an RC filter on each input with a time con-
stant of approximately 100µs (R = 10kΩ, C = 0.01µF).
Acquisition time with a 500kHz clock is 4µs. The RC fil-
ter’s settling time may increase the acquisition time
required for full accuracy when switching input channels.
