AFE for sensor interfaces

10 June 2015 Analogue, Mixed Signal, LSI

Analog Devices has introduced a FET input analog frontend (AFE) with an integrated analog-to-digital converter (ADC) driver designed to interface directly with current mode sensors such as photodiodes and high output impedance voltage sensors. The ADA4350 integrates a FET input amplifier, switching network and ADC driver into a single package. It features low-noise performance at low frequencies of 90 nV/Hz at 10 Hz and broadband noise of 5 nV/Hz at 100 kHz to maximise the signal-to-noise ratio of the sensor output. Wide dynamic range measurement for small, sensitive signals such as photons or electrons is enabled with the inclusion of integrated gain switching.
