Analog Devices Inc. (ADI, Wilmington, MA) unveiled its new difference amplifier, the AD8205, which is suited for 42V automotive systems, as well as 14V and 24V automotive systems. The AD8205 also is well suited for industrial applications that measure small differential voltages in the presence of high common-mode voltage (CMV).
The AD8205 is a high-side, current-sensing solution critical to the solenoid and motor control circuits that reside within automotive systems, such as the transmission, brakes, suspension, steering, water pumps and wipers. The AD8205 features a wide input, CMV operational range of -2V to 65V; an input CMV range of -5V to 70V; an offset drift of less than 20µV/°C; a gain drift of below 30ppm/°C (up to 125°C); a high common-mode rejection of 80dB that from dc up to 100kHz.
The AD8205 is sampling in an eight-pin SOIC package and is specified over the extended temperature range of -40°C to +125°C. The AD8205 is also available in die form, with an extended temperature range of -40°C to +150°C for use in higher temperature applications. The part is priced at $0.95 per unit in one-million-piece quantities.
