Description
(See Figure 5) The LS6511N, LS6512 and LS6513 are CMOS integrated circuits designed for detecting motion from a PIR Sensor and initiating appropriate responses.
DIFFERENTIAL AMPLIFIER Each stage of the two stage Differential Amplifier can be set to have its own amplification and bandwidth.
Features
- Direct Interface with PIR Sensor.
- Two-Stage Differential Amplifier.
- Amplifier Gain and Bandwidth externally controlled.
- True and Complementary Output Drives.
- Separate digital filters for processing positive and
negative input signals.
- Single Pulse/Dual Pulse/ Concurrent Pulse Detection.
- Adjustable Output Pulse Width.
- Optional 5V Shunt Regulator Output.
- 75µA Typical Supply Current.
- Undervoltage Detection.
