High Voltage, Precision Current Monitors for Industrial, Medical, and Automotive Applications

The AD8211 (single) and AD8213 (dual) precision current sense amplifiers feature a set gain of 20 V with a maximum 0.5% gain error over the entire industrial temperature range of –40°C to +125°C. The buffered output voltage directly interfaces with the converter. Excellent common-mode rejection from –2 V to +65 V is independent of the 5 V supply. Special circuitry is devoted to maintaining output linearity throughout the input differential range of 0 mV to 250 mV, regardless of the common-mode voltage present. The AD8213 also features additional pins that allow the user to low-pass filter the input signal before amplifying via an external capacitor to ground. This part is fully qualified per the AEC-Q100 automotive standard. Both parts are ideal for applications such as motor control, solenoid control, battery management, and power supply monitoring.

Versatile Instrumentation Amplifiers for Harsh Industrial Applications

Industrial systems, such as those used in programmable logic controllers (PLC) or power monitoring, often face tough environmental challenges—for example, the need to pack multiple channels into a tight space at elevated temperatures. The AD8226 and AD8227 instrumentation amplifiers help designers solve these challenges by offering up to 125°C operation, low power dissipation, and built-in overvoltage protection, thus eliminating external protective elements and freeing up valuable space for more channels and a denser design. They are available in a spacesaving MSOP package.

The versatile AD8226 and AD8227 work equally well on single supply rails (down to 2.7 V) or at dual industrial supply voltages (±15 V). With their wide input range and rail-to-rail output, the AD8226 and AD8227 get the most out of the voltage supply, whatever it is. The AD8226 and AD8227 are valuable choices for robust, demanding industrial applications. They stay cool even when it gets hot.
