LM393 LM393N LM393P DIP-8 Low Offset Voltage Dual Comparators

The LM393 series are dual independent precision voltage comparators capable of single or split supply operation. These devices are designed to permit a common mode range to ground level with single supply operation. Input offset voltage specifications as low as 2.0 mV make this device an excellent selection for many applications in consumer, automotive, and industrial electronics.

Features:
Wide Single Supply Range: 2.0 Vdc to 36 Vdc
Split Supply Range: 1.0 Vdc to 18 Vdc
Very Low Current Drain Independent of Supply Voltage: 0.4 mA
Low Input Bias Current: 25 nA
Low Input Offset Current: 5.0 nA
Low Input Offset Voltage: 5.0 mV (max) LM293/393

IC2262 IC2272 4 channel 4 key wireless remote control kits

Remote control :
1. Operating voltage: DC12V (27A/12V battery x1)
2. Operating Current: 10mA @ 12V
3. Radiated power: 10mw @ 12V
4. Modulation mode: ASK (Amplitude Modulation)
5. Transmitting frequency: 315MHZ (SAW frequency stabilization)
6. Transmission distance :50-100M (Open field the receiver sensitivity -100dbm)
7. Encoder types: fixed code
8. The frequency of this product is 315 mhz.

With decoding receiver board :
1.The operating voltage DC5V, receiver sensitivity is-98db. Leg 7 bits, respectively, VT, D3, D2, D1, D0, the +5 V and GND. VT is a valid signal high output pin Upon receiving a valid signal, the pin output high, may also drive the relay.
2.Size: 6.6*22*41mm

There are four buttons on the remote control, and respectively correspond to the four data bits to the receiving board output pin D0, D1, D2, and D3 of. Press the buttons transmit signals, the corresponding data bit is output high.

Module function description:
This module contains no self-locking function, simple implementation, wireless remote control by pressing a key, the receiver output a high level, the corresponding output when key releases. High level at the receiving end disappear, and each channel are independent of each other, each other. The output of high level can directly drive the relay, as shown in the shop
