The HMCAD5831LP9BE is a wideband 3-bit analog-to-digital converter with over/under range bit. The converter operates at typical speeds of up to 26 GSPS under typical conditions with a Nyquist input. Reference ladder end voltages are set externally by the user allowing the user to customize input common mode and swing levels. ADC outputs can be forced to 0 by using the Data Inhibit function. Output data can be modulated by an external clock via the XOR CML input. The HMCAD5831LP9BE also features a 1:2 demux with half rate clock output. The output bits are binary weighted, where X2 and Y2 are the MSBs. The single-ended RF input can be AC or DC coupled and supports broadband operation.

The HMCAD5831LP9BE operates from −5V and −3.3V supplies and is available in RO HS-compliant 9 × 9 mm SMT package.
