EVAALVUAAILTAIOBNLEKIT
4-/6-/8-Channel, 16-/14-Bit,
Simultaneous-Sampling ADCs
General Description
The MAX11047/MAX11048/MAX11049 and MAX11057/
MAX11058/MAX11059 16-bit/14-bit ADCs offer 4, 6, or 8
independent input channels. Featuring independent track
and hold (T/H) and SAR circuitry, these parts provide
simultaneous sampling at 250ksps for each channel.
The devices accept a 0 to +5V input. All inputs are
overrange protected with internal ±20mA input clamps
providing overrange protection with a simple external
resistor. Other features include a 4MHz T/H input band-
width, internal clock, and internal or external reference.
A 20MHz, bidirectional, parallel interface provides the
conversion results and accepts digital configuration
inputs.
The devices operate with a 4.75V to 5.25V analog supply
and a separate flexible 2.7V to 5.25V digital supply for
interfacing with the host without a level shifter. The
MAX11047/MAX11048/MAX11049 are available in a 56-pin
TQFN and 64-pin TQFP packages while the MAX11057/
MAX11058/MAX11059 are available in TQFP only. All
devices operate over the extended -40°C to +85°C tem-
perature range.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
