Qualified for automotive applications APPLICATIONS Automotive radar Adaptive cruise control Collision avoidance Blind spot detection Self parking Electronic bumper GENERAL DESCRIPTION The AD8285 is designed for low cost, low power, compact size, Fabricated in an advanced complementary metal oxide flexibility, and ease of use. It contains four channels of a low noise semiconductor (CMOS) process, the AD8285 is available in a preamplifier (LNA) with a programmable gain amplifier (PGA) 10 mm 10 mm, RoHS compliant, 72-lead LFCSP that is specified and an antialiasing filter (AAF) plus one direct to ADC channel, all over the automotive temperature range of 40C to +105C. integrated with a single 12-bit analog-to-digital converter (ADC). Table 1. Related Devices Each channel features a gain range of 16 dB to 34 dB in 6 dB Part No. Description increments and an ADC with a conversion rate of up to 72 MSPS. AD8283 6-channel LNA/PGA/AAF, pseudo simultaneous The combined input referred noise voltage of the entire channel channel sampling with ADC is 3.5 nV/Hz at maximum gain. The channel is optimized for AD8284 4-channel LNA/PGA/AAF, sequential channel dynamic performance and low power in applications where a sampling with ADC small package size is critical.
