Integrated circuits

Integrated circuits, or ICs, are circuits where certain logical or analog functions have been created by combining many transistors on a single die, resulting in a much more compact solution than one would get by using discrete transistors.

There are two main types of pagage for integrated circuits: through hole (DIP-) and surface mount (SO-). Most circuits are available in both kinds of package.

  CA3140E DIP-8 single op-amp
4.5MHz, BiMOS Operational Ampli?er with MOSFET Input/Bipolar Output The CA3140 is an integrated circuit operational amplifier that combines the advantages of high voltage PMOS transistors with high voltage bipolar transistors on a single monolithic chip. The CA3140 BiMOS operational amplifier features gate protected MOSFET (PMOS) transistors in the input circuit to provide very high input impedance, very low input current, and high speed performance. The CA3140 operates at supply voltage from 4V to 36V (either single or dual supply). These operational amplifiers are internally phase compensated to achieve stable operation in unity gain follower operation, and additionally, have access terminal for a supplementary external capacitor if additional frequency roll-off is desired. Terminals are also provided for use in applications requiring input offset voltage nulling. The use of PMOS field effect transistors in the input stage results in common mode input voltage capability down to 0.5V below the negative supply terminal, an important attribute for single supply applications. The output stage uses bipolar transistors and includes built-in protection against damage from load terminal short circuiting to either supply rail or to ground.

  LM358AN DIL-8 Low Power Dual Operational Amplifier
Low Power Dual Operational Amplifier This circuit consists of two independent, high gain, internally frequency compensated operational amplifiers which were designed specifically to operate from a single power supply over a wide range of voltages. The low power supply 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, these circuits can be directly supplied with the standard +5V which is used in logic systems and will easily provide the required interface electronics without requiring any additional power supply. In the linear mode the input common-mode voltage range includes ground and the output voltage can also swing to ground, even though operated from only a single power supply voltage. Features * Internally frequency compensated * Large DC voltage gain: 100dB * Wide bandwidth (unity gain): 1.1MHz (temperature compensated) * Very low supply current/amplifier (500uA) essentially independent of supply voltage * Low input bias current: 20nA (temperature compensated) * Low input offset voltage: 2mV * Low input offset current: 2nA * Input common-mode voltage range include ground * Differential input voltage range equal to the power supply voltage * Large output voltage swing 0V to (Vcc - 1.5V)

  SA5200D SO-8 RF-gain block dual
The SA5200 is a dual amplifier with DC to 1200MHz response. Low noise (NF = 3.6dB) makes this part ideal for RF front-ends, and a simple power-down mode saves current for battery operated equipment. Inputs and outputs are matched to 50?. The enable pin allows the designer the ability to turn the amplifiers on or off, allowing the part to act as an amplifier as well as an attenuator. This is very useful for front-end buffering in receiver applications. (industrial surplus / restparti)
