In Figure 4, the ADDRESS input provides a TTL-compatible input
to control the bus supply. A HIGH (5 V) input switches Q1 ON and sets
the bus voltage to 6 V through the resistor divider R4, R5, and Zener
Z1. A LOW input switches Q1 OFF and sets the bus voltage to 9 V
(Z1). This voltage is fed into the positive input of the operational
amplifier OP1 and is buffered and made available at BUS SUPPLY (or
sensor supply). Bus reset control is also available in the form of a TTL-
compatible input. When the RESET input is HIGH, Q2 is switched ON
and the positive input of the operational amplifier is set to the satura-
tion voltage of the transistor (approximately 0 V). This resets the bus.
A linear reading of the bus current is made possible by amplifying
the voltage generated across R6 (which is IBUS R6). The amplifier,
OP2, is a standard differential amplifier of gain R9/R7 (provided that R7
= R8, R9 = R10). The gain of the total transim-pedance amplifier is
given by:
VOUT = IBUS R6 R9/R7
This voltage is available at the ANALOG OUT terminal.
Bus Control Software
The processing of the bus current (available at ANALOG OUT) is
best done by feeding it into the A/D input of a microprocessor. If the
flexibility provided by a microprocessor is not desired, this signal could
be fed into threshold detection circuitry; e.g., comparator, and the
output used to drive a display.
