hi, Dear PL engineer
one thing need consult associated with LMP7721 as below.
my customer want TI propose a circuit to testing x-ray energy. so I propose below charger amplifier.
my customer then use LMP7721EVM board to evaluate the performance of LMP7721. however, customer find that the non-inverting inoput has ~500mV voltage difference versus inverting input. could you please help to figure out the root cause or double check? thanks.
regards,
Bill
Hi Bill,
As Clemens mentioned the total supply is too high at 11 V. The supply range is 1.8V to 5.5V on a single supply or +/-0.9 to +/-2.75V on a split supply.

Chris Featherstone
