DESCRIPTION
Maxwell Technologies’ 6484 provides a common-mode range that extends to both supply rails. This rail-to-rail performance combined with excellent accuracy, due to a high CMRR<makes it unique among rail-to-rail input amplifiers. It is ideal for systems, such as data acquisition, that require a large input signal range.
Maximum dynamic signal range is assured in low voltage and single supply systems by the 6484’s rail-to-rail output swing. The device’s rail-to-rail output swing is guaranteed for loads down to 600Ω. Guaranteed low voltage characteristics and low power dissipation make the 6484 especially well-suited for battery-operated systems.
Maxwell Technologies' patented RAD-PAK® packaging technology incorporates radiation shielding in the microcircuit package. It eliminates the need for box shielding while providing the required radiation shielding for a lifetime in orbit or space mission. In a GEO orbit, RAD-PAK provides greater than 100 krad (Si) radiation dose tolerance. This product is available with screening up toMaxwell Technologies self-defined Class K.

DESCRIPTION
The RA55H3340M is a 55-watt RF MOSFET Amplifier Module for 12.5-volt mobile radios that operate in the 330- to 400-MHz range.
The battery can be connected directly to the drain of the enhancement-mode MOSFET transistors. Without the gate voltage (VGG=0V), only a small leakage current flows into the drain and the RF input signal attenuates up to 60 dB. The output power and drain current increase as the gate voltage increases. With a gate voltage around 4V (minimum), output power and drain current increases substantially. The nominal output power becomes available at 4.5V (typical) and 5V maximum). At VGG=5V, the typical gate current is 1 mA.
This module is designed for non-linear FM modulation, but may also be used for linear modulation by setting the drain quiescent current with the gate voltage and controlling the output power with the input power.

FEATURES
*Enhancement-Mode MOSFET Transistors (IDD≅0 @ VDD=12.5V, VGG=0V)
*Pout>55W, ηT>35% @ VDD=12.5V, VGG=5V, Pin=50mW
*Broadband Frequency Range: 330-400MHz
*Low-Power Control Current IGG=1mA (typ) at VGG=5V
*Module Size: 66 x 21 x 9.88 mm
*Linear operation is possible by setting the quiescent drain current with the gate voltage and controlling the output power with the input power

GENERAL DESCRIPTION
The CS42L51 is a highly integrated, 24-bit, 96 kHz, low power stereo CODEC. Based on multi-bit, delta-sigma modulation, it allows infinite sample rate adjustment between 4 kHz and 96 kHz. Both the ADC and DAC offer many features suitable for low power, portable system applications.
The ADC input path allows independent channel control of a number of features. An input multiplexer selects between line-level or microphone level inputs for each channel. The microphone input path includes a selectable programmable-gain pre-amplifier stage and a low noise MIC bias voltage supply. A PGA is available for line or microphone inputs and provides analog gain with soft ramp and zero cross transitions. The ADC also features a digital volume attenuator with soft ramp transitions. A programmable ALC and Noise Gate monitor the input signals and adjust the volume levels appropriately.
The DAC output path includes a digital signal processing engine. Tone Control provides bass and treble adjustment of four selectable corner frequencies. The Mixer allows independent volume control for both the ADC mix and the PCM mix, as well as a master digital volume control for the analog output. All volume level changes may be configured to occur on soft ramp and zero cross transitions. The DAC also includes de-emphasis, limiting functions and a beep generator delivering tones selectable across a range of two full octaves.
The stereo headphone amplifier is powered from a separate positive supply and the integrated charge pump provides a negative supply. This allows a ground-centered analog output with a wide signal swing and eliminates external DC-blocking capacitors.
In addition to its many features, the CS42L51 operates from a low-voltage analog and digital core, making this CODEC ideal for portable systems that require extremely low power consumption in a minimal amount of space.
The CS42L51 is available in a 32-pin QFN package in both Commercial (-10 to +70° C) and Automotive grades (-40 to +85° C). The CDB42L51 Customer Demonstration board is also available for device evaluation and implementation suggestions. Please see “Ordering Information” on page 85 for complete details.

Description
The CSN Series of closed loop current sensors are based on the principles of the Magnetoresistive or Hall effects, and the null balance or zero magnetic flux method (feedback system).
The magnetic flux in the sensor core is constantly controlled at zero.
The amount of current required to balance zero flux is the measure of the primary current flowing through the conductor, multiplied by the ratio of the primary to secondary windings.
This closed loop current is the output from the device and presents an image of the primary current reduced by the number of secondary turns at any time.
This current can be expressed as a voltage by passing it through a resistor.

Features
* Current sensing up to 1200 amps
* Measures ac, dc and impulse currents
* Competitive cost/performance ratio
* Rapid response
* High overload capability
* High level of electrical isolation between primary and secondary circuits
* Industrial operating temperature range
* Small size and weight

Typical Applications
* Variable speed drives
* Overcurrent protection
* Ground fault detectors
* Current feedback control systems
* Robotics
* UPS and telecommunication power supplies
* Welding power supplies
* Automotive - Battery management systems
* Wattmeters
