HI-8573, HI-8574, HI-8575
Quad CMOS Op Amp / Comparator
DESCRIPTION
The HI-8573, HI-8574 and HI-8575 devices are designed
using low power CMOS technology. The operating
current is externally programmable with a resistor to give
the optimum tradeoff between power dissipation and slew
rate. The operational amplifiers are internally
compensated.
All three versions offer a high degree of versatility and are
well suited for both line-powered and battery-powered
systems. Features include a typical offset voltage of
±5 mV, high input impedance and low current drain.
Either single or dual power supply operation may be
used up to 15V DC. The comparators are CMOS and
TTL compatible. The three devices are direct
replacements for the Motorola/ON-Semiconductor
MC14573, MC14574 and MC14575 respectively.

PROGRAMMING CURRENT
The programming current ISET is fixed by an external re-
sistor RSET connected between VEE and either one or
both of the ISET pins (8 and 9). When two external pro-
gramming resistors are used, the set currents for each op
amp pair or comparator are given by:
ISET (mA) @ (VCC-VEE-1.0)/RSET (MW)
Pins 8 and 9 may be tied together for use with a single pro-
gramming resistor. The set currents for each op amp or
comparator pair are then given by:
ISET (mA) @ (VCC-VEE-1.0)/2 RSET (MW)
If a pair of op amps or comparators are not used, the ISET
pin for that pair may be tied to VCC for minimum power
consumption.
It should be noted that increasing ISET for comparators
will decrease propagation delay for that comparator.
For operational amplifiers, the maximum obtainable out-
put voltage (VOH) for a given load resistor connected to
VEE is given by:
VOH = (4 x 10-3 ISET)RL - 0.05V
if (4 x 10-3 ISET) RL < VCC
where, RL is in KW, ISET is in mA
Typical op amp slew rates are given by:
SR @ 0.05 ISET (V/ms).
where, ISET is in mA
