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.
