19-5036; Rev 0; 10/09 KIT ATION EVALU E L B A AVAIL 4-/6-/8-Channel, 16-Bit, Simultaneous-Sampling ADCs General Description Features ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ 4-/6-/8-Channel 16-Bit ADC Single Analog and Digital Supply High-Impedance Inputs Up to 1GΩ On-Chip T/H Circuit for Each Channel Fast 3µs Conversion Time High Throughput: 250ksps for All 8 Channels 16-Bit, High-Speed, Parallel Interface Internal Clocked Conversions 10ns Aperture Delay 100ps Channel-to-Channel T/H Matching Low Drift, Accurate 4.096V Internal Reference Providing an Input Range of ±5V ♦ External Reference Range of 3.0V to 4.25V, Allowing Full-Scale Input Ranges of ±4.0V to ±5.2V ♦ 56-Pin TQFN Package (8mm x 8mm) ♦ Evaluation Kit Available MAX11044/MAX11045/MAX11046 The MAX11044/MAX11045/MAX11046 16-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/MAX11045/MAX11046 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, 16-bit, bidirectional, parallel interface provides the conversion results and accepts digital configuration inputs. The MAX11044/MAX11045/MAX11046 operate with a 4.75V to 5.25V analog supply and a separate flexible 2.7V to 5.25V digital su...
