OPA GXX350 (compatible with OPAX350) to help sweeping robots

In the sweeping robot BMS, op-amps are mainly used for current detection, accurate current detection, you can get accurate battery capacity, battery information can also be sent to the host via SMBUS, connected to the user terminal via WIFI and other means, so that users can understand the battery health of the sweeping robot in time.

An engineer needs an OPA combined with an external sampling resistor for motor current detection, and GXSC‘s dual-channel operational amplifier GXX350 is perfect for this application. The application advantages are as follows:

1, support rail-to-rail, with a high bandwidth of 38MHz and low noise of 5nV/√Hz, high bandwidth gain and low noise can ensure the accuracy in current detection.

2, -45 ℃ ~ +125 ℃ operating temperature range can be completely stable work in the sweeping robot.

3, with completely independent circuitry to minimize crosstalk and completely eliminate interactions.

4, running on a single power supply as low as 2.5V, the input common-mode voltage range between 300mV below the ground voltage to 300mV above the positive supply.

5, The use of miniature MSOP8, SOP8, DIP8 packages can reduce PCB area.

In addition, GXX350 is compatible with TI‘s (Texas Instruments) OPAX350, which has superior performance and is ideal for use in sweeping robots.
