MAX11129–MAX11132
3Msps, Low-Power, Serial 12-/10-Bit,
8-/16-Channel ADCs
Input Bandwidth
The ADC’s input-tracking circuitry features a 1.5MHz
small-signal full-linear bandwidth to digitize high-speed
transient events and measure periodic signals with
bandwidths exceeding the ADC’s sampling rate by using
undersampling techniques. Anti-alias filtering of the input
signals is necessary to avoid high-frequency signals
aliasing into the frequency band of interest.
3-Wire Serial Interface
The MAX11129–MAX11132 feature a serial interface
compatible with SPI/QSPI and MICROWIRE devices. For
SPI/QSPI, ensure the CPU serial interface runs in master
mode to generate the serial clock signal. Select the SCLK
frequency of 48MHz or less, and set clock polarity (CPOL)
and phase (CPHA) in the FP control registers to the same
value. The MAX11129–MAX11132 operate with SCLK
idling high, and thus operate with CPOL = CPHA = 1.
Set CS low to latch input data at DIN on the rising edge
of SCLK. Output data at DOUT is updated on the falling
edge of SCLK. A high-to-low transition on CS samples
the analog inputs and initiates a new frame. A frame is
defined as the time between two falling edges of CS.
There is a minimum of 16 bits per frame. The serial data
input, DIN, carries data into the control registers clocked
in by the rising edge of SCLK. The serial data output,
DOUT, delivers the conversion results and is clocked out
by the falling edge of SCLK. DOUT is a 16-bit data word
containing a 4-bit channel address, followed by a 12-bit
conversion result led by the MSB when CHAN_ID is set
to 1 in the ADC Mode Control register (Figure 2a). In
this mode, keep the clock high for at least one full SCLK
period before the CS falling edge to ensure best perfor-
mance (Figure 2b). When CHAN_ID is set to 0 (external
clock mode only), the 16-bit data word includes a lead-
ing zero and the 12-bit conversion result is followed by
3 trailing zeros (Figure 2c). In the 10-bit ADC, the last 2
LSBs are set to 0.
