The MAX11044/MAX11045/MAX11046 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 pro-

vide simultaneous sampling at 250ksps for each channel.

The MAX11044/MAX11045/MAX11046 and MAX11054/

MAX11055/MAX11056 accept a ±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 bandwidth, internal clock, and internal or external

reference. A 20MHz, bidirectional, parallel interface

provides the conversion results and accepts digital

configuration inputs.

The MAX11044/MAX11045/MAX11046 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.

are available in a 56-pin TQFN and 64-pin TQFP pack-

ages while the MAX11054/MAX11055/MAX11056 are

available in TQFP only and operate over the extended

-40°C to +85°C temperature range.
