Dual Channel Current Sensor achieves a 100 dB dynamic range to visual-
ize low-power device operations

The CX1102A Dual Channel Current Sensor enables simultaneous measurements under
two different measurement ranges. For example, the primary channel is set to a 200 mA
range, while the secondary channel is to a 2 mA range (primary channel range is 50
or 100 times of secondary channel). This current sensor is very useful for low-power
applications that periodically operate in both sleep/standby state and active state.

Figure 15. The CX1103A Low Side Current Sensor
employs offset adjustable ultra-wideband
transimpedance technology, which can cancel
the large DC current offset and extract only the
required dynamic current. This feature is quite
useful to measure low-level dynamic sensor
current signals on a larger DC current.

The CX1152A Digital Channel is useful when you need digital triggers to measure current
synchronized with digital signals such as controller’s I/O or data bus up to 8 channels.
Unlike conventional digital probes, each probe for the CX1152A has large 10 MΩ input
resistance, which enables you to make accurate low power measurements by minimizing
the load current.
