MAX11044ETN+

The MAX11044ETN+ is a 4-channel, 16bit, simultaneous sampling ADC in 56 pin TQFN package. It features independent track and hold (T/H) and SAR circuitry, this device provide simultaneous sampling at 250Ksps for each channel. The device accepts 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. It operates with a 4.75V to 5.25V analogue supply and a separate flexible 2.7V to 5.25V digital supply for interfacing with the host without a level shifter. Typical applications include automatic test equipment, power-factor monitoring and correction, power-grid protection, multiphase motor control and vibration and waveform analysis.
