LM1894 [Dynamic Noise Reduction System DNR® ]

other parts : LM1894M  LM1894MX  LM1894N 

National-Semiconductor
National ->Texas Instruments

General Description
The LM1894 is a stereo noise reduction circuit for use with audio playback systems. The DNR system is non-complementary, meaning it does not require encoded source material. The system is compatible with virtually all prerecorded tapes and FM broadcasts. Psychoacoustic masking, and an adaptive bandwidth scheme allow the DNR to achieve 10 dB of noise reduction. DNR can save circuit board space and cost because of the few additional components required.

Features
Non-complementary noise reduction, “single ended”
Low cost external components, no critical matching
Compatible with all prerecorded tapes and FM
10 dB effective tape noise reduction CCIR/ARM weighted
Wide supply range, 4.5V to 18V
1 Vrms input overload

Applications
Automotive radio/tape players
Compact portable tape players
Quality HI-FI tape systems
VCR playback noise reduction
Video disc playback noise reduction

MAX1894 [Advanced Li+ Battery-Pack Protectors ]

other parts : MAX1894-MAX1924  MAX1894XEEE  MAX1924  MAX1924VEEE  MAX1924XEEE 

MaximIC
Maxim Integrated

General Description
The MAX1894/MAX1924 are lithium-ion/lithium-polymer (Li+) battery-pack protector ICs for 3- or 4-series Li+ bat tery packs. The MAX1894/MAX1924 enhance the useful operating life of Li+ batteries by monitoring individual cell voltages and preventing over/undervoltage conditions. The MAX1894/MAX1924 also protect the battery pack against charge current, discharge current, and pack short fault conditions.

Features
♦ Protect Against Cell Overvoltage
   Factory Programmable Limits from 4V to 4.4V Accurate to ±0.5%
♦ Protect Against Cell Undervoltage Factory Programmable Limits from 2V to 3.2V Accurate to ±2.0%
♦ Protect Against Charge, Discharge, and Pack Short Current Faults
♦ Automatically Trickle Charges Deeply Discharged Cells
♦ Fully Integrated MOSFET Drivers Do Not Require Pullup Resistors
♦ 0.8µA (typ) Shutdown Supply Current Prevents Deep Discharge of Cells
♦ 30µA (typ) Operating Supply Current
♦ 28V (max) Input Voltage
♦ Available in Small 16-Pin QSOP Package

Applications
  3- or 4-Series Li+ Battery Packs
