The ACPL-C79B-000E is a precision miniature Isolation Amplifier designed for current and voltage sensing in electronic power converters. It operates from a single 5V supply and provides excellent linearity and dynamic performance of 60dB SNR. The amplifier with 200kHz bandwidth, 1.6µs fast response time, the product captures transients in short-circuit and overload conditions. The high common-mode transient immunity provides the precision and stability needed to accurately monitor motor current in high noise motor control environments, providing for smoother control in various types of motor control applications. In a typical motor drive implementation, current flows through an external resistor and the resulting analogue voltage drop is sensed by the isolation amplifier.

• Advanced sigma-delta A/D converter technology
• Fully differential isolation amplifier
• Compact and auto-insertable standard
• 15kV/μs Common-mode transient immunity
• 0.05% Excellent linearity

The LM2900N is a general purpose quadruple Norton Operational Amplifier consist of four independent, high-gain frequency-compensated Norton operational amplifiers that were designed specifically to operate from a single supply over a wide range of voltages. Operation from split supplies is also possible. The low supply current drain is essentially independent of the magnitude of the supply voltage. These devices provide wide band-width and large output voltage swing.

• Wide range of supply voltages, single or dual supplies
• Wide bandwidth
• Large output voltage swing
• Output short-circuit protection
• Internal frequency compensation
• Low input bias current
