Integrerade kretsar


Integrerade kretsar ("IC-kretsar") är kretsar där en viss logisk eller analog funktion realiserats genom att kombinera ett antal transistorer på samma kiselbricka. Detta gör att samma funktion kan realiseras på mindre yta än om den realiserats med diskreta transistorer.

Det finns huvudsakligen två typer av kapsling för integrerade kretsar; hålmonterade (DIP-) och ytmonterade (SO-). De flesta kretsar finns i både hålmonterat och ytmonterat utförande.

  LM5110-3M SO-8 Dual 5A Compound Gate Driver with Neg
A output: inverting B output: non-inverting The LM5110 Dual Gate Driver replaces industry standard gate drivers with improved peak output current and efficiency. Each compound output driver stage includes MOS and bipolar transistors operating in parallel that together sink more than 5A peak from capacitive loads. Combining the unique characteristics of MOS and bipolar devices reduces drive current variation with voltage and temperature. Separate input and output ground pins provide Negative Drive Capability allowing the user to drive MOSFET gates with positive and negative VGS voltages. The gate driver control inputs are referenced to a dedicated input ground (IN_REF). The gate driver outputs swing from VCC to the output ground VEE which can be negative with respect to IN_REF. The ability to hold MOSFET gates off with a negative VGS voltage reduces losses when driving low threshold voltage MOSFETs often used as synchronous rectifiers. When driving with conventional positive only gate voltage, the IN_REF and VEE pins are connected together and referenced to a common ground. Under-voltage lockout protection and a shutdown input pin are also provided. The drivers can be operated in parallel with inputs and outputs connected to double the drive current capability. 5A sink/3A source current capability n Two channels can be connected in parallel to double the drive current n Independent inputs (TTL compatible) n Fast propagation times (25 ns typical) n Fast rise and fall times (14 ns/12 ns rise/fall with 2 nF load) n Dedicated input ground pin (IN_REF) for split supply or single supply operation n Outputs swing from VCC to VEE which can be negative relative to input ground n Available in dual non-inverting, dual inverting and combination configurations n Shutdown input provides low power mode n Supply rail under-voltage lockout protection n Pin-out compatible with industry standard gate drivers

  OP290GP DIP-8 dual op-amp
Precision, Low Power, Micropower Dual Operational Amplifier The OP290 is a high performance micropower dual op amp that operates from a single supply of 1.6V to 36V or from dual supplies of +/-0.8 V to +/-18 V. Input voltage range includes the negative rail allowing the OP290 to accommodate input signals down to ground in single-supply operation. The OP290s output swing also includes ground when operating from a single supply, enabling "zero-in, zero-out" operation. The OP290 draws less than 20uA of quiescent supply current per amplifier, while able to deliver over 5mA of output current to a load. Input offset voltage is below 200uV eliminating the need for external nulling. Gain exceeds 700000 and common-mode rejection is better than 100dB. The power supply rejection ratio of under 5.6uV/V minimizes offset voltage changes experienced in battery-powered systems. The low offset voltage and high gain offered by the OP290 bring precision performance to micropower applications. The minimal voltage and current requirements of the OP290 suit it for battery- and solar-powered applications, such as portable instruments, remote sensors, and satellites. For a single op amp, see the OP90; for a quad, see the OP490.
