PRODUCTION DATA
Refer to the PDF data sheet for device specific package drawings
The OPA561 has separate circuits to monitor the positive and negative currents. Each output is compared to a single internal reference that is set by the external current limit resistor (or voltage). The OPA561 employs a patented circuit technique to achieve an accurate and stable current limit. The output current limit has an accuracy of up to 5% on the 1-A current limit. Due to internal matching limitations, the positive and negative current limits can be slightly different. However, the values are typically within 10% of each other.
