MULTI-BUFFERED A-TO-D CONVERTER (MibADC)
SPNS110E – AUGUST 2005 – REVISED MAY 2008 ......................................................................................................................................................... www.ti.com
The multi-buffered A-to-D converter (MibADC) has a separate power bus for its analog circuitry that enhances
the A-to-D performance by preventing digital switching noise on the logic circuitry, which could be present on VSS
and VCC, from coupling into the A-to-D analog stage. All A-to-D specifications are given with respect to ADREFLO
unless otherwise noted.
