High Sensitivity Current Input Interface
Description
TPA8801B is a high sensitivity current input interface, which can covert the p A to n A range current signal to 5V range output. TPA8801B use one resister to set the transduce gain, can provide ideal 4.56GΩ current to voltage DC gain when the resister is 20KΩ. As the output is...
