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.
19-5106; Rev 2; 1/11
Note: All devices are specified over the -40°C to +85°C operating
temperature range.
+ Denotes a lead(Pb)-free/RoHS-compliant package.
