AD8285 is a low-cost, low-power, small-sized, and flexible product, with features such as 4-channel LNA, PGA, and AAF. It is suitable for applications such as automotive radar, adaptive cruise control, collision avoidance system, blind spot detection, automatic parking, and electronic bumpers.
The AD8285 is an integrated chip designed for low-cost, low-power, and small-size applications. It features four channels of Low Noise Amplifier (LNA), Programmable Gain Amplifier (PGA), and Anti-Aliasing Filter (AAF), all connected to a single 12-bit Analog-to-Digital Converter (ADC). The device supports programmable gain from 16 dB to 34 dB in 6 dB steps and includes a programmable third-order low-pass elliptic filter with cutoff frequencies ranging from 1.0 MHz to 12.0 MHz.
The AD8285 is manufactured using advanced CMOS technology and comes in a 72-lead, 10 mm × 10 mm LFCSP package compliant with RoHS standards. It operates over an automotive temperature range of -40°C to +105°C. Key specifications include a maximum sampling rate of 72 MSPS, a signal-to-noise ratio (SNR) of up to 68.5 dB, and low input-referred voltage noise. This manual is written in Chinese.
