ZHCSH14A November 2017 – December 2017 OPA2333P
PRODUCTION DATA.
This single-supply, low-side, bidirectional current-sensing solution detects load currents from –1 A to 1 A. The single-ended output spans from 110 mV to 3.19 V. This design uses the OPA2333P because of its low offset voltage and rail-to-rail input and output. One of the amplifiers is configured as a difference amplifier and the other provides the reference voltage.
Figure 23 shows the solution.
