General Description
The MAX11044/MAX11044B/MAX11045/MAX11045B/
MAX11046/MAX11046B 16-bit and MAX11054/MAX11055/
MAX11056 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 MAX11044/MAX11044B/MAX11045/MAX11045B/
MAX11046/MAX11046B and MAX11054/MAX11055/
MAX11056 accept a ±5V input. All inputs are overrange pro-
tected with internal ±20mA input clamps providing over-
range protection with a simple external resistor. Other
features include a 4MHz T/H input bandwidth, internal clock,
and internal or external reference. A 20MHz, bidirectional,
parallel interface provides the conversion results and
accepts digital configuration inputs.
The MAX11044/MAX11044B/MAX11045/MAX11045B/
MAX11046/MAX11046B and MAX11054/MAX11055/
MAX11056 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 MAX11044/
MAX11044B/MAX11045/MAX11045B/MAX11046/
MAX11046B are available in a 56-pin TQFN and 64-pin
TQFP packages while the MAX11054/MAX11055/
MAX11056 are available in TQFP only and operate over
the extended -40°C to +85°C temperature 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.
ELECTRICAL CHARACTERISTICS
(VAVDD = +4.75V to +5.25V, VDVDD = +2.70V to +5.25V, VAGNDS = VAGND = VDGND = 0V, VREFIO = internal reference, CRDC = 4 x
33μF, CREFIO = 0.1μF, CAVDD = 4 x 0.1μF || 10μF, CDVDD = 3 x 0.1μF || 10μF; all digital inputs at DVDD or DGND, unless otherwise
noted, fSAMPLE = 250ksps. TA = -40°C to +85°C, unless otherwise noted. Typical values are at TA = +25°C.)
