NATIONAL SEMICONDUCTOR - LMV1032-06/LMV1032-15/LMV1032-25 Amplifiers for 3 Wire Analog Electret Microphones handbook
LMV1032 is an audio amplifier series designed for small form factor electret microphones. It is intended to replace the JFET preamp currently used. The LMV1032 series is ideal for applications requiring extended battery life, such as a Bluetooth communication link. The addition of a third pin in electret microphones incorporating the LMV1032 allows for a significant reduction in supply current compared to JFET-equipped electret microphones, reducing microphone supply current to 60µA, ensuring longer battery life. The LMV1032 series is guaranteed for supply voltages from 1.7V to 5V and has fixed voltage gains of 6dB, 15dB, and 25dB. The LMV1032 series offers low output impedance over the voice bandwidth, excellent power supply rejection (PSRR), and temperature stability. The devices are offered in a space-saving 4-bump ultra-thin micro SMD lead-free package, making them ideally suited for the form factor of miniature electret microphone packages.

NATIONAL SEMICONDUCTOR LM2576/LM2576HV Series SIMPLE SWITCHER 3A Step-Down Voltage Regulator Manual
The LM2576 series of regulators are monolithic integrated circuits that provide all the active functions for a step-down (buck) switching regulator, capable of driving 3A load with excellent line and load regulation. These devices are available in fixed output voltages of 3.3V, 5V, 12V, 15V, and an adjustable output version. Requiring a minimum number of external components, these regulators are simple to use and include internal frequency compensation and a fixed-frequency oscillator. The LM2576 series offers a high-efficiency replacement for popular three-terminal linear regulators. It substantially reduces the size of the heat sink, and in some cases no heat sink is required. A standard series of inductors optimized for use with the LM2576 are available from several different manufacturers. This feature greatly simplifies the design of switch-mode power supplies. Other features include a guaranteed ±4% tolerance on output voltage within specified input voltages and output load conditions, and ±10% on the oscillator frequency. External shutdown is included, featuring 50 µA (typical) standby current. The output switch includes cycle-by-cycle current limiting, as well as thermal shutdown for full protection under fault conditions.

NATIONAL SEMICONDUCTOR LMX2487E Manual
The LMX2487E is a low power, high performance delta-sigma fractional-N PLL with an auxiliary integer-N PLL. It is fabricated using National Semiconductor's advanced process. With delta-sigma architecture, fractional spurs at lower offset frequencies are pushed to higher frequencies outside the loop bandwidth. The ability to push close in spur and phase noise energy to higher frequencies is a direct function of the modulator order. Unlike analog compensation, the digital feedback technique used in the LMX2487E is highly resistant to changes in temperature and variations in wafer processing. The LMX2487E delta-sigma modulator is programmable up to fourth order, which allows the designer to select the optimum modulator order to fit the phase noise, spur, and lock time requirements of the system. Serial data for programming the LMX2487E is transferred via a three line high speed (20 MHz) MICROWIRE interface. The LMX2487E offers fine frequency resolution, low spurs, fast programming speed, and a single word write to change the frequency. This makes it ideal for direct digital modulation applications, where the N counter is directly modulated with information. The LMX2487E is available in a 24 lead 4.0 X 4.0 X 0.8 mm LLP package.

NATIONAL SEMICONDUCTOR LM117/LM317A/LM317 3-Terminal Adjustable Regulator Manual
The LM117 series of adjustable 3-terminal positive voltage regulators is capable of supplying in excess of 1.5A over a 1.2V to 37V output range. They are exceptionally easy to use and require only two external resistors to set the output voltage. Further, both line and load regulation are better than standard fixed regulators. Also, the LM117 is packaged in standard transistor packages which are easily mounted and handled. In addition to higher performance than fixed regulators, the LM117 series offers full overload protection available only in IC's. Included on the chip are current limit, thermal overload protection and safe area protection. All overload protection circuitry remains fully functional even if the adjustment terminal is disconnected. Normally, no capacitors are needed unless the device is situated more than 6 inches from the input filter capacitors in which case an input bypass is needed. An optional output capacitor can be added to improve transient response. The adjustment terminal can be bypassed to achieve very high ripple rejection ratios which are difficult to achieve with standard 3-terminal regulators. Besides replacing fixed regulators, the LM117 is useful in a wide variety of other applications. Since the regulator is “floating” and sees only the input-to-output differential voltage, supplies of several hundred volts can be regulated as long as the maximum in
NATIONAL SEMICONDUCTOR DS15EA101 0.15 to 1.5 Gbps Adaptive Cable Equalizer with LOS Detection Manual
The DS15EA101 is an adaptive equalizer optimized for equal- izing data transmitted over copper cables. It operates over a wide range of data rates from 150 Mbps to 1.5+ Gbps and automatically adapts to equalize any cable length from zero meters to lengths that attenuate the signal by 35 dB at 750 MHz. It allows either single-ended or differential in- put drive, which enables equalization of coaxial cables as well as differential twin-ax and twisted pair cables. It also features an LOS output and an output en- able which, when tied together, disable the output when no signal is present. The DS15EA101 is powered from a single 3.3V supply and consumes 210 mW at 1.5 Gbps. It operates over the full −40°C to +85°C industrial temperature range and is available in a space saving 4 x 4 mm LLP-16 package which allows for high density placement of components in multi-channel ap- plications.
