LM311 Voltage Comparator IC DIP-8
The LM311 devices are single high-speed voltage comparators. These devices are designed to operate from a wide range of power supply voltages, including ?15-V supplies for operational amplifiers and 5-V supplies for logic systems. The output levels are compatible with most TTL and MOS circuits. These comparators are capable of driving lamps or relays and switching voltages up to 50 V at 50 mA. All inputs and outputs can be isolated from system ground. The outputs can drive loads referenced to ground, VCC or VCC?. Offset balancing and strobe capabilities are available, and the outputs can be wire-OR connected. If the strobe is low, the output is in the off state, regardless of the differential input.

LM317 IC – Variable Voltage Regulator IC
The LM317 is an adjustable three-terminal positive-voltage regulator capable of supplying more than 1.5 A over an output-voltage range of 1.25 V to 37 V. It is exceptionally easy to use and requires only two external resistors to set the output voltage. Furthermore, both line and load regulation are better than standard fixed regulators
LM317T
LM317 is monolithic integrated circuits in TO-220, TO-220FP, D?PAK
and SOT223 packages intended for use as positive adjustable voltage regulators.
They are designed to supply more than 1.5 A of load current with an output voltage
adjustable over a 1.2 to 37 V range.
The nominal output voltage is selected by means of a resistive divider, making
the device exceptionally easy to use and eliminating the stocking of many fixed
regulators
LM324 Low Power Quad Op-Amp IC DIP-14
The LM324IC series are low?cost, quad operational amplifiers with true differential inputs. They have several distinct advantages over
standard operational amplifier types in single supply applications. The quad amplifier can operate at supply voltages as low as 3.0 V or as high as 32 V with quiescent currents about one?fifth of those associated with the MC1741 (on a per amplifier basis). The common-mode input range includes the negative supply, thereby eliminating the necessity for external biasing components in many applications. The
output voltage range also includes the negative power supply voltage.
