TILT BLOCK: TILT SENSOR NORMALIZATION CIRCUIT
In normal mode (ADTST = 0) the normalization block
produces a normalized tilt error signal TILTN according to:
(2)
where ADOC is a drop-out concealed reference current
with:
ADOC = 1 if (TS1 + TS2) > ITT
ADOC = (TS1 + TS2)/ITT if (TS1+TS2) < ITT
The signal TILTN is sent as D1 to the output if Q/NE = 0.
A copy is sent to the MON block (see Fig.12).
7.2.8
OUTPUT CURRENT POLARITIES
The currents TILTN, FEN, REN and TLN are bipolar
currents and are sent to D1 to D4 if Q/NE = 0. The
currents MIRN and PW are unipolar and are sent to
S1 and S2 if Q/NE = 0. They are negative according to the
definition used in this document, i.e. sourced by the
device. If Q/NE = 1 the input currents Q1 to Q6 are
transferred directly to D1 to D4, S1 and S2. They are, in
general, bipolar currents.
