LM2675M-3.3/NOPB
The LM2675 series operates at a switching frequency
of 260 kHz, thus allowing smaller-sized filter
components than what would be needed with lower
frequency switching regulators. Because of its very
high efficiency (>90%), the copper traces on the
printed-circuit board are the only heat sinking needed.

LM2676S-3.3
The LM2676 series of regulators are monolithic
integrated circuits which provide all of the active
functions for a step-down (buck) switching regulator
capable of driving up to 3-A loads with excellent line
and load regulation characteristics. High efficiency
(>90%) is obtained through the use of a low ONresistance DMOS power switch. The series consists
of fixed output voltages of 3.3-V, 5-V, and 12-V and
an adjustable output version.
The SIMPLE SWITCHER?
concept provides for a
complete design using a minimum number of external
components. A high fixed frequency oscillator
(260 kHz) allows the use of physically smaller sized
components. A family of standard inductors for use
with the LM2676 are available from several
manufacturers to greatly simplify the design process.

LM2902D
This circuit consists of four independent, highgain operational amplifiers (op amps) which
employ internal frequency compensation and are
specifically designed for automotive and
industrial control systems.
The device operates from a single power supply
over a wide range of voltages. Operation from
split power supplies is also possible and the lowpower supply current drain is independent from
the power supply voltage magnitude.
LM2902M
The LM124-N series consists of four independent,
high-gain, internally frequency compensated
operational amplifiers designed to operate from a
single power supply over a wide range of voltages.
Operation from split-power supplies is also possible
and the low-power supply current drain is
independent of the magnitude of the power supply
voltage.
Application areas include transducer amplifiers, DC
gain blocks and all the conventional op amp circuits
which now can be more easily implemented in single
power supply systems. For example, the LM124-N
series can directly operate off of the standard 5-V
power supply voltage which is used in digital systems
and easily provides the required interface electronics
without requiring the additional ?15 V power supplies
LM2917M-8
The LM2907 and LM2917 devices are monolithic
frequency-to-voltage converters with a high gain op
amp designed to operate a relay, lamp, or other load
when the input frequency reaches or exceeds a
selected rate. The tachometer uses a charge pump
technique and offers frequency doubling for lowripple, full-input protection in two versions (8-pin
LM2907 and LM2917), and its output swings to
ground for a zero frequency input.
The op amp is fully compatible with the tachometer
and has a floating transistor as its output. This feature
allows either a ground or supply referred load of up to
50 mA. The collector may be taken above VCC up to a
maximum VCE of 28 V.
LM293H
The LM193-N series consists of two independent
precision voltage comparators with an offset voltage
specification as low as 2.0 mV max for two
comparators which were designed specifically to
operate from a single power supply over a wide range
of voltages. Operation from split power supplies is
also possible and the low power supply current drain
is independent of the magnitude of the power supply
voltage. These comparators also have a unique
characteristic in that the input common-mode voltage
range includes ground, even though operated from a
single power supply voltage.
