LM1872 Datasheet Radio Control Receiver/decoder

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: LM1872 Radio Control Receiver Decoder February 1989 LM1872 Radio Control Receiver.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The LM1872 is a plete RF receiver decoder for radio control applications The device is well suited for use at either 27 MHz 49 MHz or 72 MHz in controlling various toys or hobby craft such as cars boats tanks trucks robots planes and trains The crystal controlled superhet design offers both good sensitivity and selectivity When operated in conjunction with the panion transmitter LM1871 it provides four independent information channels Two of these channels are analog pulse width modulated (PWM) types while the other two are simple ON OFF digital channels with 100 mA drive capability Either channel type can be converted to the other form through simple external circuitry such that up to 4 analog or up to 4 digital channels could be created Few external parts are required to plement the self-contained device which includes local oscillator mixer IF detector AGC sync output drivers and all decoder logic on-chip

Key Features

  • Y Y Y Y Y Y Y Y Y Y Four independent information channels two analog and two digital Completely self-contained Minimum of external parts Operation from 50 kHz to 72 MHz Highly selective and sensitive superhet design Operates from four 1 5V cells Excellent supply noise rejection 100 mA digital output drivers Crystal controlled Interfaces directly with standard hobby servos.
