Не могу сделать нормальный перевод на русский, чтобы не резало ушей. Переводчики не помогают. Может вы поможете?
Further Pin Details
Pin 3 Offset Filter. Connects to an external 10uF capacitor & holds the average value of the switched
capacitor bypass filter output. Motion is detected when the difference between this average and the actual filter output is greater than the sensitivity setting.
Pin 4 Anti-Alias. Connects to external 0.1uF providing low-pass filtering of the PIR signal input signal blocking input signals at and above the switching frequency of the switched capacitor bypass filter.
Pin 5 DC Cap. Connects to an external 10uF and holds the average source potential. The difference between this average & the actual source potential is amplified & coupled to the switched capacitor bypass filter. It should be a low-leakage or tantalum capacitor.
Pin 6 Vreg. This is supposed to be a voltage regulator pin. However, we found it did not work as advertised & we used an external voltage regulator.
Pin 7 Drain Reference. The potential is power supply independent. The potential can be divided down by an external pot to supply the sensitivity adjust to pin 2.
Pin 8 Source. PIR input. It is sensitive and should be as short a length as possible. There should be a ground plane
on the PCB under the sensor.
Pin 9 is Analog ground and Pin 10 is Digital Ground
Pin 13 Gain Select. When unconnected gain is 68db. When connected to ground gain is 62db. We have left it
unconnected here.
Pin 14 On/Auto/Off. Unconnected the IC works automatically. Connected to ground the IC will turn off unconditionally. Connected to Vcc it will turn on unconditionally.
Pin 15 Toggle. Unconnected the IC works automatically. Connected to ground the IC state will turn change its state
and remain in the new state unconditionally as long as the pin is connected to ground. We have configured this
feature to give a delay. If there is a conflict between pins 14 & 15 the off state is the default.
Pin 16 Output. Can direct small DC loads (50mA Max.) e.g. triac, optocoupler or small relay. Output impedence is 35R
allowing it to direct drive a small (100R coil resistance) relay.
Pin 20 Frequency Reference. 160Hz is used to drive the internally switched capacitor, bandpass filter & timing
delays. It is connected externally through a 60K resistor to Vcc and a 0.1uF capacitor to Gnd.

Sid Manson: Да блин, а чего тут переводить? Тут же элементарный технический язык. Никаких извратов нет. Так что не ленись, бери словарь в руки и вперед. Мне лично влом писать столько. Может кто и напишет.
