is 3.5 nV/√Hz at maximum gain. The channel is optimized for  
dynamic performance and low power in applications where a  
small package size is critical.  
GENERAL DESCRIPTION  
The AD8283 is designed for low cost, low power, compact size,  
flexibility, and ease of use. It contains six channels of a low noise  
preamplifier (LNA) with a programmable gain amplifier (PGA)  
and an antialiasing filter (AAF) plus one direct-to-ADC  
channel, all integrated with a single 12-bit analog-to-digital  
converter (ADC).  
Fabricated in an advanced CMOS process, the AD8283 is  
available in a 10 mm × 10 mm, RoHS-compliant, 72-lead  
LFCSP. It is specified over the automotive temperature range of  
−40°C to +105°C.  
Each channel features a gain range of 16 dB to 34 dB in 6 dB  
increments and an ADC with a conversion rate of up to 80 MSPS.  
The combined input-referred noise voltage of the entire channel  
Rev. 0
