PRECAUTION USE
Input Stage
q Input stages are consisted of differential circuit of NPN Tr, and have built-in IB compensation
circuit.
Built-in Driver
. Each channel driver consists of BTL configuration linear amplifier.
. Voltage gain is fixed : GV=15.5dB (Typ.)
q Voltage loss for output stage is 21/BE+VCE (sat) for positive cycle, VCE (sat) for negative cycle,
because of no-bootstrap circuit. So, output DC voltage is designed as less than 1/2Vcc.
" Terminal
. VRI is reference voltage terminal for input signal.
. If reference voltage from servo IC drop less than 1.8V, protection circuit operates and shut off
bias circuit inside. This operation is to prevent load from moving undesirably in case of VRI drop
for accident or some reason.
I/ty Terminal
. Output DC voltage is determined by circuit of this terminal inside as ;
VCI =VOUT(DC) = (Vcc-VF)/ 2
. Output signal dynamic range is depend on VCC- On the other hand, input signal dynamic range
is determined by VRI as mentioned and voltage gain is fixed inside. So, maximum output voltage
does not increase as VCC increases.
. Because of BTL configuration, Ripple Rejection Ratio does not improve not much when capacitor
is connected to VCI terminal to GND.
. Large signal GND is for output stage and smallsignal GND is for stages from input circuit to
pre-output stage.
. These GND pins are not connected inside.
. Phin0) and Phin© are connected to Bedflame, and it is connected to substrate.
. It is advised that you make a Printed Board layout of small signal GND and large signal GND
should be isolated each other.
Oscillation preventive capacitor
q We recommend to use the capacitor of 0.1pF, between each output terminals. But perform the
temperature test to check the oscillation allowance, since the oscillation allowance is varied
according to the causes described below.
1) Supply voltage
2) Ambient temperature
3) Load impedance
4) Capacity value of condenser
5) Kind of condenser
6) Layout of Printed board
We recommend to connect Pass-condenser, which is about 10 to 100pF between VRI terminal and
VCI terminal is recommend to use "OPEN".
