Featuring independent track and hold (T/H) and 8-Channel ADC (MAX11046/MAX11046B/MAX11056) SAR circuitry, these parts provide simultaneous sampling 6-Channel ADC (MAX11045/MAX11045B/MAX11055) at 250ksps for each channel. 4-Channel ADC (MAX11044/MAX11044B/MAX11054) The MAX11044/MAX11044B/MAX11045/MAX11045B/ MAX11046/MAX11046B and MAX11054/MAX11055/ Single Analog and Digital Supply MAX11056 accept a 5V input. All inputs are overrange pro- High-Impedance Inputs Up to 1G tected with internal 20mA input clamps providing over- range protection with a simple external resistor. Other On-Chip T/H Circuit for Each Channel features include a 4MHz T/H input bandwidth, internal clock, Fast 3s Conversion Time and internal or external reference. A 20MHz, bidirectional, parallel interface provides the conversion results and High Throughput: 250ksps for Each Channel accepts digital configuration inputs. 16-Bit/14-Bit, High-Speed, Parallel Interface The MAX11044/MAX11044B/MAX11045/MAX11045B/ Internal Clocked Conversions MAX11046/MAX11046B and MAX11054/MAX11055/ MAX11056 operate with a 4.75V to 5.25V analog supply and 10ns Aperture Delay a separate flexible 2.7V to 5.25V digital supply for interfacing 100ps Channel-to-Channel T/H Matching with the host without a level shifter. The MAX11044/ MAX11044B/MAX11045/MAX11045B/MAX11046/ Low Drift, Accurate 4.096V Internal Reference MAX11046B are available in a 56-pin TQFN and 64-pin Providing an Input Range of 5V TQFP packages while the MAX11054/MAX11055/ External Reference Range of 3.0V to 4.25V, MAX11056 are available in TQFP only and operate over Allowing Full-Scale Input Ranges of 4.0V to 5.2V the extended -40C to +85C temperature range.
