MAX11047MAX11049/MAX11057MAX11059 19-5106 Rev 2 1/11 4-/6-/8-Channel, 16-/14-Bit, Simultaneous-Sampling ADCs General Description Features 16-Bit ADC (MAX11047/MAX11048/MAX11049) The MAX11047/MAX11048/MAX11049 and MAX11057/ MAX11058/MAX11059 16-bit/14-bit ADCs offer 4, 6, or 8 14-Bit ADC (MAX11057/MAX11058/MAX11059) independent input channels. Featuring independent track 4-Channel ADC (MAX11047/MAX11057) and hold (T/H) and SAR circuitry, these parts provide 6-Channel ADC (MAX11048/MAX11058) simultaneous sampling at 250ksps for each channel. 8-Channel ADC (MAX11049/MAX11059) The devices accept a 0 to +5V input. All inputs are Single Analog and Digital Supply overrange protected with internal 20mA input clamps High-Impedance Inputs Up to 1G providing overrange protection with a simple external On-Chip T/H Circuit for Each Channel resistor. Other features include a 4MHz T/H input band- width, internal clock, and internal or external reference. Fast 3s Conversion Time A 20MHz, bidirectional, parallel interface provides the High Throughput: 250ksps for Each Channel conversion results and accepts digital configuration 16-/14-Bit, High-Speed, Parallel Interface inputs. Internal Clocked Conversions The devices operate with a 4.75V to 5.25V analog supply 10ns Aperture Delay and a separate flexible 2.7V to 5.25V digital supply for 100ps Channel-to-Channel T/H Matching interfacing with the host without a level shifter. The MAX11047/MAX11048/MAX11049 are available in a 56-pin Low Drift, Accurate 4.096V Internal Reference Providing an Input Range of 0 to 5V TQFN and 64-pin TQFP packages while the MAX11057/ MAX11058/MAX11059 are available in TQFP only. All External Reference Range of 3.0V to 4.25V, Allowing Full-Scale Input Ranges of +3.7V to devices operate over the extended -40C to +85C tem- +5.2V perature range. 56-Pin TQFN (8mm x 8mm) and 64-Pin TQFP Applications (10mm x 10mm) Packages Automatic Test Equipment Evaluation Kit Available (MAX11046EVKIT+) Power-Factor Monitoring and Correction Functional Diagram Power-Grid Protection Multiphase Motor Control AVDD DVDD Vibration and Waveform Analysis DB15** CH0 16-/14-BIT ADCs CLAMP S/H Ordering Information DB4 PART PIN-PACKAGE CHANNELS DB3/CR3 MAX11047ETN+ 56 TQFN-EP* 4 CH7 DB0/CR0 16-/14-BIT ADCs CLAMP S/H MAX11047ECB+ 64 TQFP-EP* 4 MAX11048ETN+ 56 TQFN-EP* 6 CONFIGURATION WRb AGNDS REGISTERS MAX11048ECB+ 64 TQFP-EP* 6 RDb CSb MAX11049ETN+ 56 TQFN-EP* 8 INTERFACE CONVST AND MAX11049ECB+ 64 TQFP-EP* 8 SHDN AGND CONTROL EOCb MAX11047/MAX11048/MAX11049/ MAX11057ECB+ 64 TQFP-EP* 4 MAX11057/MAX11058/MAX11059 DGND MAX11058ECB+ 64 TQFP-EP* 6 INT REF 10k RDC BANDGAP REF MAX11059ECB+ 64 TQFP-EP* 8 BUF REFERENCE Note: All devices are specified over the -40C to +85C operating EXT REF REFIO RDC SENSE* temperature range. +Denotes a lead(Pb)-free/RoHS-compliant package. *CONNECTED INTERNALLY ON THE TQFN PARTS *EP = Exposed pad. **MAX11047/MAX11048/MAX11049 MAX11049/MAX11059 Maxim Integrated Products 1 For pricing, delivery, and ordering information, please contact Maxim Direct at 1-888-629-4642, or visit Maxims website at www.maxim-ic.com.
