LS6512 Overview
(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. The two inputs to the first stage allow for single-ended or differential connection to PIR Sensors.
