AD7689BCPZRL7

AD7689BCPZRL7 is the tape-and-reel LFCSP-20 ordering code for the Analog Devices AD7689 16-bit successive-approximation ADC, in production per the AD7682/AD7689 datasheet Rev. K ordering guide. The B grade holds integral nonlinearity to ±0.4 LSB typical (±1.5 LSB maximum) with no missing codes at 16 bits, and throughput scales with supply: 250 kSPS across a 4.5 V to 5.5 V supply and 200 kSPS across the wider 2.3 V to 4.5 V range. Signal-to-noise ratio is 93.5 dB typical and total harmonic distortion is -100 dB typical, at a typical consumption of 12.5 mW at 5 V and full throughput. The selection point is dynamic range per square millimetre: near-100 dB-class performance in a 4 x 4 mm package suits portable data acquisition, medical instruments and industrial measurement front ends, and the wide supply range lets one design run from battery or 5 V rails. Selection advice: the B grade is the tighter-linearity option in this family - confirm the grade letter when comparing quotes, since the family shares package and pinout across grades but not the linearity specification. Parameters verified against the Analog Devices AD7682/AD7689 datasheet Rev. K (B-grade specifications and ordering guide).
