LS6522 Overview
(See Figure 2) The LS6522 is a CMOS integrated circuit, designed for detecting motion from a PIR Sensor and initiating appropriate responses. The detailed description of the functional blocks is as follows: DIFFERENTIAL AMPLIFIER Each stage of the two stage Differential Amplifier can be set to have its own amplification and bandwidth.
