### ⭐⭐⭐⭐ Won't measure 50A peak (35 rms) with 3.3v supply. Wrong op-amp choice, small holes...
*by J***K on April 6, 2023*

The holes are stupidly small! This is a nice chip from Allegro, but #1 issue: op-amp choice of this board is wrong. A 40mV per amp, a 50 amp peak (35A RMS if AC volts), the output at Vcc of 5v will be Vcc/2 + 2 = 4.5 volts. The 2272C op amp has a Vcc-1.5v or 5v - 1.5v = 3.5 volts, so the buffered output will clip the output. The unbuffered output ou1 should look good. (I didn't test this). The op amp should be a rail to rail *input* model, not just rail-rail output! #2 issue the chip is output limited If using it at 3.3v supply. The idle voltage of Vcc/2 = 1.65 v so with 40mV per amp sensitivity, the output range limits the current range to 1.65/0.04 = 41.25 volts (29 amps RMS with sinusoid AC). So, if you need 50A peak / 35A RMS, then skip the buffered output, power at 5v and use your own op amp on the unbuffered output IF you need to bias the output for a 3.3 volt A/D input. If you need 3.3v yet are OK being limited at 28 amps, use the unbuffered output without the opamp. That said, the unbuffered output might be fine, just don't load it with a low impedance.
