R123H7G(HS)
1. Application
This Specification is applied to inspection and approval of the IR Receiver Module for TV, DVD, STB etc
2. Description
The Series are miniaturized receiver for infrared remote control system.The PIN Photodiode and preamplifier are assembled on lead frame. The epoxy pacakge is designed as IR Filter.The module has excellent performance even in disturbed ambient light application and provides protectionagainst uncontrolled output pulses.
3. Features
1)High ripple rejection
2)Wide operating supply voltage : 2.7V ~ 6.0V
3)Low current consumption : 3.0V(0.4mA), 5.0V(0.5mA)
4)Band pass filter center frequency : 37.9KHz
5)Epoxy IR filter characteristic : 940nm
6)Maximum interference safety against optical and electrical disturbance
7)Internal filter for a high frequency lighting fluorescent lamp
8)Internal pull-up output : 50k
4. Absolute Maximum Ratings
1)Supply voltage : 0 ~ 7.0V
2)Supply current : 0 ~ 3.0?
3)Output current : 0 ~ 2.0?
4)Operating temperature : -20℃ ~ +80℃
5)Storage temperature : -30℃ ~ +85℃
6)Reflow soldering temperature (Pb Free) : 260℃(Max 10 sec)
5. Cautions
1)Store and use where there is no force causing transformation or change in quality.
2)Store and use where there is no extreme humidity.
3)In order to prevent damage from static electricity, make sure that the human body and the soldering iron are connected to ground before using.
4)The ripple noise from power supply lines may shorten detecting distance of IR receiver module. Thus, in order to ensure more reliable operating please add RC filter(R=100R, C=47uf) between Vcc and GND.
5)When a disturbance signal is applied to the series, it can still receive the data signal. However the sensitivity is reduced to the level that no unexpected pulses will occur. Some examples of such disturbance signals which can be suppressed pulses by the series.
