- TTL and CMOS compatibility
- Output active low
- Improved shielding against electrical field disturbance
- Suitable burst length ≥6 cycles/burst
Description
DESCRIPTION:
The TSOP 1838 is a member of IR remote control receiver series. This IR sensor module consists of a PIN diode and a pre amplifier which are embedded into a single package. The output of TSOP is active low and it gives +5V in off state. When IR waves, from a source, with a centre frequency of 38 kHz incident on it, its output goes low.
Lights coming from sunlight, fluorescent lamps etc. may cause disturbance to it and result in undesirable output even when the source is not transmitting IR signals. A bandpass filter, an integrator stage and an automatic gain control are used to suppress such disturbances.
FEATURES:
- Photo detector and preamplifier in one package
- Internal filter for PCM frequency
- TTL and CMOS compatibility
- Output active low
- Improved shielding against electrical field disturbance
- Suitable burst length ≥6 cycles/burst
SPECIFICATION:
- Small size package
- Enhanced immunity against all kinds of disturbance light
- No occurrence of disturbance pulses at the output
- Short settling time after power on (<200s)

NDP6020P (P-CHANNEL)
If you’ve ever wondered how to control high current devices from a low-power microcontroller, a MOSFET is what you need. The NDP6020P is a very common MOSFET with very low on-resistance and a control voltage (aka gate voltage) that is compatible with most 5V and 3.3v microcontroller or mechanical switches. This allows you to control high-power devices with very low-power control mechanisms.
TIP33B
Commonly used for general–purpose power amplifier and switching applications.
