Product Details
TPA8801B-TR - TPA8801B High-Sensitivity Current Input Interface
TPA8801B-TR from 3PEAK is a precision pA-to-nA current-input analog front end that converts very small sensor currents into a voltage output.
Specifications were checked against the manufacturer data sheet and current distributor listing.
Overview
TPA8801B combines a low-bias precision amplifier and configurable transimpedance network for dust sensors, photodiodes and other current-output sensors.
Key Advantages
1 pA typical input bias supports measurement down to approximately 100 pA.
A single external gain resistor and AC-coupling network tailor sensitivity and remove DC offset.
Available in an established surface-mount or through-hole ordering format.
Electrical and environmental limits are defined by the official data sheet.
Feature Summary
