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.

  SAA6579 DIP-16 RDS demodulator
Radio Data System (RDS) demodulator GENERAL DESCRIPTION The integrated CMOS circuit SAA6579 is an RDS demodulator. It recovers the additional inaudible RDS information which is transmitted by FM radio broadcasting. The data signal RDDA and the clock signal RDCL are provided as outputs for further processing by a suitable decoder (microcomputer). The operational functions of the device are in accordance with the "CENELEC EN 50067". FEATURES * Anti-aliasing filter (2nd order) * Integrated 57 kHz band-pass filter (8th order) * Reconstruction filter (2nd order) * Clocked comparator with automatic offset compensation * 57 kHz carrier regeneration * Synchronous demodulator for 57 kHz modulated RDS signals * Selectable 4.332/8.664 MHz crystal oscillator with variable dividers * Clock regeneration with lock on biphase data rate * Biphase symbol decoder with integrate and dump functions * Differential decoder * Signal quality detector * Subcarrier output
  AD781JNZ DIP-8 single op-amp sample-hold
FEATURES Acquisition Time to 0.01%: 700 ns Maximum Low Power Dissipation: 95 mW Low Droop Rate: 0.01 mV/ms Fully Specified and Tested Hold Mode Distortion Total Harmonic Distortion: 80 dB Maximum Aperture Jitter: 75 ps Maximum Internal Hold Capacitor Self-Correcting Architecture 8-Pin Mini Cerdip and Plastic Package MIL-STD-883 Compliant Versions Available PRODUCT DESCRIPTION The AD781 is a high speed monolithic sample-and-hold amplifier (SHA). The AD781 guarantees a maximum acquisition time of 700 ns to 0.01% over temperature. The AD781 is specified and tested for hold mode total harmonic distortion and hold mode signal-to-noise and distortion. The AD781 is configured as a unity gain amplifier and uses a self-correcting architecture that minimizes hold mode errors and insures accuracy over temperature. The AD781 is self-contained and requires no external components or adjustments. The low power dissipation, 8-pin mini-DIP package and completeness make the AD781 ideal for highly compact board layouts. The AD781 will acquire a full-scale input in less than 700 ns and retain the held value with a droop rate of 0.01 mV/ms. Excellent linearity and hold mode dc and dynamic performance make the AD781 ideal for 12- and 14-bit high speed analogto- digital converters. The AD781 is manufactured on Analog Devices BiMOS process which merges high performance, low noise bipolar circuitry with low power CMOS to provide an accurate, high speed, low power SHA. The AD781 is specified for three temperature ranges. The J grade device is specified for operation from 0°C to +70°C, the A grade from 40°C to +85°C and the S grade from 55°C to +125°C. The J and A grades are available in 8-pin plastic DIP packages. The S grade is available in an 8-pin cerdip package.
  MAX809STRG SOT-23-3 Övervakningskrets 2.93V uP reset
The MAX809 are cost-effective system supervisor circuits designed to monitor VCC in digital systems and provide a reset signal to the host processor when necessary. No external components are required. The reset output is driven active within 10 sec of VCC falling through the reset voltage threshold. Reset is maintained active for a timeout period which is trimmed by the factory after VCC rises above the reset threshold. The MAX810 has an active-high RESET output while the MAX809 has an active-low RESET output. Both devices are available in SOT-23 and SC-70 packages. The MAX809/810 are optimized to reject fast transient glitches on the VCC line. Low supply current of 0.5 A (VCC = 3.2 V) makes these devices suitable for battery powered applications. Features Precision VCC Monitor for 1.5 V, 2.5 V, 3.0 V, 3.3 V, and 5.0 V Supplies Precision Monitoring Voltages from 1.2 V to 4.9 V Available in 100 mV Steps Four Guaranteed Minimum Power-On Reset Pulse Width Available (1 ms, 20 ms, 100 ms, and 140 ms) RESET Output Guaranteed to VCC = 1.0 V. Low Supply Current Compatible with Hot Plug Applications VCC Transient Immunity No External Components Wide Operating Temperature: -40°C to 105°C Pb-Free Packages are Available Typical Applications Computers Embedded Systems Battery Powered Equipment Critical Microprocessor Power Supply Monitoring

  AT42QT1010-TSHR SOT-23-6 Qtouch 1ch sensor
Digital burst mode, charge-transfer (QT) sensor capable of detecting near-proximity or touch. It features a 'max on' setting which allows the key to re-calibrate to detect subsequent touches when faced with an obstruction for a prolonged period of time. The sensor projects a touch or proximity field to several centimeters through any dielectric including glass, plastic, stone, ceramic, and even most kinds of wood. It can turn small metal-bearing objects into intrinsic sensors, making them responsive to proximity or touch. It is designed specifically for human interfaces and includes all hardware and signal processing functions necessary to provide stable sensing under a wide variety of changing conditions. Only a single low-cost capacitor is required for operation. Parameter Value Pin Count: 6 Touch Sensor Type: Buttons # of Touch Channels: 1 Temp. Range (deg C): -40 to 85 Operating Voltage (Vcc): 1.8-5.5 Interface Type: Digital Output Acquisition Method: QTouch
