Audio Power Amplifier
The LM380 is a power audio amplifier for consumer application. In order to hold system cost to a minimum, gain is internally fixed at 34 dB. A unique input stage allows inputs to be ground referenced. The output is automatically self centering to one half the supply voltage. The output is short circuit proof with internal thermal limiting. The package outline is standard dual-in-line. A copper lead frame is used with the center three pins on either side comprising a heat sink. This makes the device easy to use in standard p-c layout. Uses include simple phonograph amplifiers, intercoms, line drivers, teaching machine outputs, alarms, ultrasonic drivers, TV sound systems, AM-FM radio, small s...

LM381/LM381A Low Noise Dual Preamplifier
The LM381 LM381A is a dual preamplifier for the amplification of low level signals in applications requiring optimum noise performance Each of the two amplifiers is completely independent with individual internal power supply decoupler-regulator providing 120 dB supply rejection and 60 dB channel separation Other outstanding features include high gain (112 dB) large output voltage swing (VCC b 2V) p-p and wide power bandwidth (75 kHz 20 Vp-p) The LM381 LM381A operates from a single supply across the wide range of 9V to 40V Either differential input or single ended input configurations may be selected The amplifier is internally compensated with the provision for additional external compensat...
LM3812
manufacturer
National Semiconductor
Precision Current Gauge-IC
The LM3812/LM3813 Current Gauges provide easy to use precision current measurement with virtually zero insertion loss (typically 0.004Ω). The LM3812 is used for high-side sensing and the LM3813 is used for low-side sensing. A Delta Sigma analog to digital converter is incorporated to precisely measure the current and to provide a current averaging function. Current is averaged over 50 msec time periods in order to provide immunity to current spikes. The ICs have a pulse-width modulated (PWM) output which indicates the current magnitude and direction. The shutdown pin can be used to inhibit false triggering during start-up, or to enter a low quiescent current mode. The LM3812 and LM3813 are f...
