Fig.39 Typical application diagram for voltage mechanisms.
(1) For crystal oscillator see Figs 3 and 4.
(2) 1.5 nF capacitors connected between
pins LN and LP, and RN and RP must
be placed as near to the pins as
possible. This also applies to the
220 nF and 47
μ
F capacitors
connected between pins V
neg
and
V
. Power supplies and V
reference inputs (
1
V
) for DAC
operational amplifiers must be low
noise.
(3) For connections between OEIC and
TZA1025, refer to TZA1025 device
specification.
(4) Components for LP filter and V
→
I
conversion depend on OEIC and
current range set on CD10II.
