• 64 Lead Plastic 9 x 9 mm SMT Package: 81 mm2 Functional Diagram General Description
The HMCAD5831LP9BE is a wideband 3-bit analogto-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 singleended 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 ROHS-compliant 9 x 9 mm
SMT package. Electrical Specifications, TA = +25 °C [1] , AVEE = -5 V, OVEE = -3.3 V, Full-Scale Vin = 256 mV, Clock Input Power = 0 dBm (single ended)
