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 supply for interfacing with the host without a level shifter. The MAX11044/MAX11045/MAX11046 are available in a 56-pin TQFN package and operate over the extended -40°C to +85°C temperature range. † Ordering Information PART MAX11044ETN+ MAX11045ETN+ MAX11046ETN+ PIN-PACKAGE 56 TQFN-EP* 56 TQFN-EP* 56 TQFN-EP* CHANNELS 4 6 8 Applications Automatic Test Equipment Power-Factor Monitoring and Correction Power-Grid Protection Multiphase Motor Control Vibration and Waveform Analysis †Patent pending.
