Dedicated current sensors and accessories to meet the wide variety of
measurement needs for your applications
Providing a wide application coverage without compromising both wide bandwidth
and low noise requirements is quite challenging. Accessories for the CX3300 series are
dedicated to wideband low-level current waveform measurements and help you meet
various application needs.
The CX1101A covers wide measurement ranges from 40 nA to 10 A and operates under
higher common mode voltage up to ±40 V. The CX1102A enables the equivalent of a
100 dB (5-decade) dynamic range at a single measurement, which is useful when you
measure a current waveform for both sleep/standby and active states at one time.
The CX1103A can be used for what is known as low side current sensing and features
the series minimum measurable current (150 pA at 20 MHz bandwidth) and the series
maximum bandwidth (200 MHz sensor alone).
The CX3300 series also offers voltage measurement capability by using a Passive Probe
Interface Adapter (CX1151A) and a Digital Channel (CX1152A) up to 8 channels. See
the “CX3300 Series Selection Guide” to find out which accessory can be used for your
applications.

Despite the wide dynamic range measurement capability, the minimum equivalent series
resistance of CX1101A and CX1102A current sensors is minimized to 410 mΩ typ. for wide
measurement ranges. As a result, you don’t have to worry about a large voltage drop
(burden voltage) across the internal resistor (see Figure 28).
