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.

  OPA177GP DIP-8  single op-amp precision
Precision Operational Amplifier The OPA177 precision bipolar op amp feature very low offset voltage and drift. Laser-trimmed offset, drift and input bias current virtually eliminate the need for costly external trimming. The high performance and low cost make them ideally suited to a wide range of precision instrumentation. The low quiescent current of the OPA177 dramatically reduce warm-up drift and errors due to thermoelectric effects in input interconnections. It provides an effective alternative to chopper-stabilized amplifiers. The low noise of the OPA177 maintains accuracy. Features * Low offset voltage: 25uV max. * Low drift: 0.3uV/°C * High open-loop gain: 130dB min. * Low quiescent current: 1.5mA typ. * Replaces industry-standard op amps: OP-07, OP-77, OP-177, AD707, etc. Applications * Precision instrumentation * Data acquisition * Test equipment * Bridge amplifier * Thermocouple amplifier

  LM334Z TO-92 Justerbar strömgenerator
LM334 är en justerbar konstantströmsgenerator. Den kan användas för strömbegränsning tillsammans med en op-förstärkare, som en temperaturgivare eller som en variabel, konstantströmsgenerator för diverse applikationer. Utgångsströmmen bestäms av ett externt motstånd. För att ge en helt linjär temperaturkoefficient krävs endast ett motstånd och en diod. * Matningsspänning: 1 - 40V * Tolerans: 3% * Strömområde: 1uA - 10mA * Temperaturkoefficient: 0.33%/°C

  FST3253MX SO-16 Switch
Dual 4:1 Multiplexer/Demultiplexer Bus Switch The Fairchild Switch FST3253 is a dual 4:1 high-speed CMOS TTL-compatible multiplexer/demultiplexer bus switch. The low on resistance of the switch allows inputs to be connected to outputs without adding propagation delay or generating additional ground bounce noise. When OE is LOW, S0 and S1 connect the A Port to the selected B Port output. When OE is HIGH, the switch is OPEN and a high-impedance state exists between the two ports. Features * 4ohm switch connection between two ports. * Minimal propagation delay through the switch. * Low Icc. * Zero bounce in flow-through mode. * Control inputs compatible with TTL level.

  MAX619CPA DIP-8 5V Step-up regulator
Regulated 5V Charge-Pump DC-DC Converter The MAX619 step-up charge-pump DC-DC converter delivers a regulated 5V ±4% output at 50mA over temperature. The input voltage range is 2V to 3.6V (two battery cells). The complete MAX619 circuit fits into less than 0.1in2 of board space because it requires only four external capacitors: two 0.22uF flying capacitors, and 10uF capacitors at the input and output. Low operating supply current (150uA max) and low shutdown supply current (1uA max) make this device ideal for small, portable, and battery-powered applications. When shut down, the load is disconnected from the input. Features * Regulated 5V ±4% Charge Pump * Output Current Guaranteed over Temperature - 20mA (VIN = 2V) - 50mA (VIN = 3V) * 2V to 3.6V Input Range * No Inductors; Very Low EMI Noise * Ultra-Small Application Circuit (0.1in2) * Uses Small, Inexpensive Capacitors * 500kHz Internal Oscillator * Logic-Controlled 1µA Max Shutdown Supply Current * Shutdown Disconnects Load from Input Applications * Two Battery Cells to 5V Conversion * Local 3V-to-5V Conversion * Portable Instruments & Handy-Terminals * Battery-Powered Microprocessor-Based Systems * 5V Flash Memory Programmer * Minimum Component DC-DC Converters * Remote Data-Acquisition Systems * Compact 5V Op-Amp Supply * Regulated 5V Supply from Lithium Backup Battery * Switching Drive Voltage for MOSFETs in * Low-Voltage Systems
