MAX11040K/MAX11060
24-/16-Bit, 4-Channel, Simultaneous-Sampling,
Cascadable, Sigma-Delta ADCs
EVALUATION KIT AVAILABLE
General Description
The MAX11040K/MAX11060 are 24-/16-bit, 4-channel,
simultaneous-sampling, sigma-delta analog-to-digital
converters (ADCs). The devices allow simultaneous
sampling of as many as 32 channels using a built-in
cascade feature to synchronize as many as eight
devices. The serial interface of the devices allows read-
ing data from all the cascaded devices using a single
command. Four modulators simultaneously convert
each fully differential analog input with a programmable
data output rate ranging from 0.25ksps to 64ksps. The
devices achieve 106dB SNR at 16ksps and 117dB SNR
at 1ksps (MAX11040K). The devices operate from a
single +3V supply. The differential analog input range is
±2.2V when using the internal reference; an external
reference is optional. Each input is overvoltage protect-
ed up to ±6V without damage. The devices use an
internal crystal oscillator or an external source for clock.
The devices are compatible with SPI, QSPI,
MICROWIRE, and DSP-compatible 4-wire serial inter-
faces. An on-board interface logic allows one serial inter-
face (with a single chip select) to control up to eight
cascaded devices or 32 simultaneous sampling analog
input channels.
The devices are ideally suited for power-management
systems. Each channel includes an adjustable sam-
pling phase enabling internal compensation for phase
shift due to external dividers, transformers, or filters at
the inputs. The output data rate is adjustable with a
0.065% resolution (at 16ksps or below) to track the
varying frequency of a periodic input. A SYNC input
allows periodic alignment of the conversion timing of
multiple devices with a remote timing source.
The devices are available in a 38-pin TSSOP package speci-
fied over the -40°C to +105°C industrial temperature range.
