| Info: |
MPXA4115A (Motorola’s MPX4115A/MPXA4115A series sensor integrates on–chip, bipolar op amp
circuitry and thin film resistor networks to provide a high output signal and temperature
compensation. The small form factor and high reliability of on–chip integration make the
Motorola pressure sensor a logical and economical choice for the system designer.
The MPX4115A/MPXA4115A series piezoresistive transducer is a state–of–the–art,
monolithic, signal conditioned, silicon pressure sensor. This sensor combines advanced
micromachining techniques, thin film metallization, and bipolar semiconductor processing to
provide an accurate, high level analog output signal that is proportional to applied pressure.
Figure 1 shows a block diagram of the internal circuitry integrated on a pressure
sensor chip.
Features
• 1.5% Maximum Error over 0° to 85°C
• Ideally suited for Microprocessor or Microcontroller–
Based Systems
• Temperature Compensated from –40° to +125°C
• Durable Epoxy Unibody Element or Thermoplastic
(PPS) Surface Mount Package
Application Examples
• Aviation Altimeters
• Industrial Controls
• Engine Control
• Weather Stations and Weather Reporting Devices) |

Signal generator |
| Date: |
Monday, 27-August-2007 |
| Info: |
A signal generator, also known variously as a test signal generator, function generator, tone generator, arbitrary waveform generator, or frequency generator is an electronic device that generates repeating electronic signals (in either the analog or digital domains). They are generally used in designing, testing, troubleshooting, and repairing electronic or electroacoustic devices; though they often have artistic uses as well. |

| Info: |
An oscilloscope (sometimes abbreviated CRO, for cathode-ray oscilloscope, or commonly just scope or O-scope) is a piece of electronic test equipment that allows signal voltages to be viewed, usually as a two-dimensional graph of one or more electrical potential differences (vertical axis) plotted as a function of time or of some other voltage (horizontal axis). |

nRF905 Multiband Transceiver |
| Date: |
Thursday, 5-July-2007 |
| Info: |
nRF905 is a single-chip radio transceiver for the 433/868/915 MHz ISM band. The transceiver consists of a fully integrated frequency synthesiser, receiver chain with demodulator, a power amplifier, a crystal oscillator and a modulator. The ShockBurst™ feature automatically handles preamble and CRC. Configuration is easily programmable by use of the SPI interface. Current consumption is very low, in transmit only 11mA at an output power of -10dBm, and in receive mode 12.5mA. Built in power down modes makes power saving easily realizable |
