Multiple range current measurement system with low power dissipation, fast settling time, and low common mode voltage error |
摘要 |
A multi-range measuring circuit for measuring a flow of electrical current between a first node and a second node. A measurement resistor is connected to the first node to develop a voltage having a high range output. A summing node connected in series with the measurement resistor acts as an input to an amplifier for developing a second voltage having a low range output having a higher scale factor than the high range output. If the capacity of the amplifier to maintain the low range as a linear function is exceeded, a bypass circuit bypasses excess current flow to the second node.
