DESCRIPTION
The AT5005 is a high voltage isolation amplifier designed for multiple applications where input signals are measured, processed, or transmitted without a galvanic connection . These isolation amplifiers in SIP or DIP package offer a signal and power isolation function. With internal transformer-coupling, th e AT5005 provides total galvanic isolation between the input and output stages of the isolation amplifier. These amplifiers eliminate the need for an external DC-DC converter, which allows the designer to minimize the necessary circuit overhead, thus reducing the overall design and component costs. The AT5005 is powered directly from a 15V DC power supply, featuring small size, high accuracy, low power, wide bandwidth, excellent performance, flexible input, isolated power, etc. INSIDE THE AT5005 The AT 5005 uses an amplitude modulation technique to permit transformer coupling of signals down to dc (Figure 1). It also contains an uncommitted input op amp and a power transformer that provides isolated power to the op amp, the modulator, and any external load. The power transformer primary is driven by a 25kHz, 15VP-P square wave generated internally. Optical Fiber Figure 1. AT5005 Functional Block Diagram
