MAX11056ECB+

The MAX11056ECB+ is an 8-channel, 14bit, simultaneous-sampling ADC in 64 pin TQFP package. Featuring independent track and hold (T/H) and SAR circuitry, it also provides simultaneous sampling at 250Ksps for each channel. All inputs are overrange protected with internal ±20mA input clamps providing overrange protection with a simple external resistor. Other features such as 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. Typical applications include automatic test equipment, power-factor monitoring and correction, power-grid protection, multiphase motor control and vibration and waveform analysis.
