Utilizing the circuit designs perfected for Quad Operational Amplifiers, these dual operational amplifiers feature low power drain, a common mode input voltage range extending to ground/VEE, and single supply or split supply operation. The LM358S and LM2904S are half of the LM324S and LM2902S, respectively. These amplifiers have several distinct advantages over standard operational amplifier types in single supply applications. 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.

The LM393S and LM2903S are dual, independent, precision voltage comparators capable of single or split supply operation. These devices are designed to permit a common mode range to ground level with single supply operation. Input offset voltage specifications as low as 2.0 mV make this device an excellent selection for many applications in consumer, automotive, and industrial electronics.

The LM431A / LM431B / LM431C are three terminal output adjustable regulators with thermal stability over the full operating temperature range. The output voltage can be set to any value between VREF(approximately 2.5 V) and 36 V with two external resistors. These devices have a typical dynamic output impedance of 0.2 Ω. Active output circuit provides a sharp turn-on characteristic, making these devices excellent replacements for Zener diodes in many applications.

The LM555 is a highly stable controller capable of producing accurate timing pulses. With monostable operation, the time delay is controlled by one external resistor and one capacitor. With a stable operation, the frequency and duty cycle are accurately controlled with two external resistors and one capacitor.

The LM7301 series of operational amplifiers provide high performance in a wide range of applications. The benefits include greater than rail-to-rail input range, full rail-to-rail output swing, large capacitive load driving ability and low distortion. With only 0.6 mA supply current, the 4 MHz gain-bandwidth of this device supports new portable applications where higher power devices unacceptably drain battery life.The LM7301 series can be driven by voltages that exceed both power supply rails, thus eliminating concerns over exceeding the common-mode voltage range. The rail-to-rail output swing capability provides the maximum possible dynamic range at the output. This is particularly important when operating on low supply voltages. Operating on supplies of 1.8 V to 32 V, the LM7301 is excellent for a very wide range of applications in low power systems. Placing the amplifier right at the signal source reduces board size and simplifies signal routing. The LM7301 fits easily on low profile PCMCIA cards.
