The ADC124S021 is a low-power, four-channel CMOS 12-bit analog-to-digital converter with a high-speed serial interface. Unlike the conventional practice of specifying performance at a single sample rate only, the ADC124S021 is fully speci- fied over a sample rate range of 50 kSPS to 200 kSPS. The converter is based on a successive-approximation register architecture with an internal track-and-hold circuit. It can be configured to accept up to four input signals at inputs IN1 through IN4. The output serial data is straight binary, and is compatible with several standards, such as SPI™, QSPI™, MICROW- IRE, and many common DSP serial interfaces. The ADC124S021 operates with a single supply that can range from +2.7V to +5.25V. Normal power consumption using a +3V or +5V supply is 2.2 mW and 7.9 mW, respec- tively. The power-down feature reduces the power consump- tion to just 0.14 µW using a +3V supply, or 0.32 µW using a +5V supply. The ADC124S021 is packaged in a 10-lead MSOP package. Operation over the industrial temperature range of −40˚C to +85˚C is guaranteed.

The product is an audio codec that can provide 18-bit Sigma-Delta ADCs and DACs, providing 90dB of dynamic range. The product is designed specifically for PC audio systems, with full duplex stereo ADCs and DACs and analog mixers that can access 4 stereo and 4 mono inputs. Each mixer input has separate gain, attenuation and mute control, and the mixers drive 1 mono and 2 stereo outputs, each with attenuation and mute control. The product also supports National’s 3D Sound stereo enhancement and a comprehensive sample rate conversion capability. The ADCs and DACs’ sample rates can be programmed separately with a resolution of 1Hz to convert any rate in the range 4kHz-48kHz. ADCs’ sample timing and DACs’ sample request timing are completely deterministic to ease task scheduling and application software development. These features and the extended temperature range also make the LM4550B suitable for non-PC codec applications. The product has the ability to connect multiple codecs together in a system to provide up to 6 equivalent stereo audio channels.

The AD8561 is a single 7 ns comparator with separate input and output sections. Separate supplies enable the input stage to be operated from ±5 V dual supplies and +5 V single supplies. Fast 7 ns propagation delay makes the AD8561 a good choice for timing circuits and line receivers. Propagation delays for rising and falling signals are closely matched and track over temperature. This matched delay makes the AD8561 a good choice for clock recovery, since the duty cycle of the output will match the duty cycle of the input. The AD8561 has the same pin configuration as the AD8562 and AD8563 and comes in the same packages.

AD7329 is a 1 MSPS, 8-channel, software-selectable, true bipolar input, 12-bit plus sign ADC

The XFA-0201-15BH is a surface mount transformer with a frequency range of 0.075-200 MHz and an impedance ratio of 1:1.5. It is designed for applications in broadband, wireless communication systems, and other similar fields. It offers small size, low cost, and high reliability.

The MAX3869 is a complete, single +3.3V laser driver for SDH/SONET applications up to 2.5Gbps. The device accepts differential PECL data and clock inputs and provides bias and modulation currents for driving a laser. A synchronizing input latch can be used (if a clock signal is available) to reduce jitter. An automatic power control (APC) feedback loop is incorporated to maintain a constant average optical power over temperature and lifetime. The wide modulation current range of 5mA to 60mA and bias current of 1mA to 100mA are easy to program, making this product ideal for use in various SDH/SONET applications. The MAX3869 also provides enable control, two current monitors that are directly proportional to the laser bias and modulation currents, and a failure-monitor output to indicate when the APC loop is unable to maintain the average optical power. The MAX3869 is available in 32-pin TQFP and small 32-pin QFN packages as well as dice.

Hand brushes are used everywhere, in the metal industry, construction work, in the workshop. They are found in every tool box. The complete range contains all types of filling materials, from coarse steel to the finest brass wire. The handles are made of beech wood with two hanging holes. LESSMANN-Handbrushes are of superb quality and yet are eco- nomic due to a fully automated and efficient production facility. Using modern marking systems indi- vidual printing of brands and EAN Bar Codes can be made. This is done by burning stamps or tampon printing at low cost. All above list- ed hand brushes have a bar code stamp. Environmental hint: LESSMANN hand brushes with a wooden body are certified in accordance with PEFC standards.
