AD8418AWBRZ, SOIC-8 Current-Sensing Amplifiers
см. техническую документацию
Описание
AD8418A is a bidirectional, zero drift, current sense amplifier. It is a high voltage, high resolution current shunt amplifier. It features an initial gain of 20V/V, with a maximum ±0.15% gain error over the entire temperature range. The buffered output voltage directly interfaces with any typical converter. This amplifier performs bidirectional current measurements across a shunt resistor in a variety of automotive and industrial applications, including motor control, power management, and solenoid control, low-side current sensing, diagnostic protection etc. It includes EMI filters and patented circuitry to enable output accuracy with pulse-width modulation (PWM) type input common-mode voltages.
• Typical 0.1µV/°C offset drift, slew rate is 1V/µs
• Maximum ±200µV voltage offset over full temperature range
• Operating power supply range is 2.7V to 5.5V
• Electromagnetic interference (EMI) filters included
• Common-mode rejection ratio (CMRR) is 90dB minimum
• Initial gain is 20V/V, bidirectional operation
• Operating temperature range is -40°C to +125°C
• Packaging style is 8-lead SOIC
• N
• Qualified for automotive applications
