Analog Devices Inc. AD8410A Current-Sense Amplifiers provide an initial gain of 20V/V, with a 2.2MHz bandwidth with a maximum ±0.13% gain error over the entire temperature range. The AD8410A high voltage, high bandwidth current-sense amplifiers offer a minimum DC common-mode rejection ratio (CMRR) of 123dB from -2V to +70V. The device’s buffered output voltage directly interfaces with any typical converter. The AD8410A performs bidirectional current measurements over a shunt resistor in various industrial and automotive applications.
The ADI AD8410A current-sense amplifiers supply an in-package trim core, which leads to a typical offset drift of ±0.21µV/°C throughout the operating temperature range and the common-mode voltage range. The amps contain circuitry to perform a wide input common-mode range and balanced input bias currents, regardless of input differential or common-mode voltage, and circuitry to execute ultra-low CMRR drift. The AD8410A also incorporates circuitry to enable output accuracy in the presence of pulse-width modulation (PWM) type input common mode voltages.
The AD8410A operates throughout the -40°C to +125°C temperature range and is available in an 8-lead SOIC_N package.
