ADA4350ARUZ

ADA4350 is an analogue front end with ADC driver for photodetectors or other sensors whose output produces a current proportional to the sensed parameter or voltage input applications where the system requires the user to select between very precise gain levels to maximize the dynamic range. This integrates a FET input amplifier, a switching network, and an ADC driver with all functions controllable via a serial peripheral interface (SPI) or parallel control logic into a single IC. The FET input amplifier has very low voltage noise and current noise making it an excellent choice to work with a wide range of photodetectors, sensors, or precision data acquisition systems. Application includes current to voltage (I to V) conversions, photodiode preamplifiers, chemical analysers mass spectrometry, molecular spectroscopy, laser/LED receivers, and data acquisition systems.

• Low noise, low input bias current FET input amplifier
• Very low input bias current is ±0.25pA typical at 25°C

• Temperature rating range from -40°C to +85°C
• 28-lead thin shrink small outline package [TSSOP]
