General Description

TPA8801B is a high sensitivity current input interface, which can covert the pA to nA 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 saturated in the real application by offset voltage of internal amplifier, AC coupled mode is used to remove DC offset voltage and bias current impaction, so the real AC gain in the application is less than ideal DC gain depend on the capacitor values.
