Pololu ACS724 Current Sensor Carrier (±5A) Features a high 120 kHz bandwidth for faster response times Allows the user to filter the output for improved resolution at lower bandwidth Offers an integrated digital temperature compensation circuitry for nearly closed loop accuracy Has an automotive-grade operating temperature range of -40 to 150 °C This Pololu ACS724 Current Sensor Carrier (±5A) is a simple carrier of Allegro’s bidirectional ±5A ACS724LLCTR-05AB Hall effect-based linear current sensor, which offers a low-resistance (~1.2 mΩ) current path and electrical isolation up to 2.4 kV RMS. This version accepts a bidirectional current input with a magnitude up to 5 A and outputs a proportional analog voltage (400 mV/A) centered at 2.5 V with a typical error of ±1.5%. It operates from 4.5 V to 5.5 V and is intended for use in 5 V systems. It offers an integrated digital temperature compensation circuitry allows for a nearly closed loop accuracy over the temperature in an open loop sensor.
