AD40xx 16/18-Bit SAR ADCs Analog Devices AD40xx family features low-noise, low-power, precision 16-/18-Bit successive approximation register (SAR) ADCs that achieve high performance with throughputs up to 2MSPS. Operating from a 1.8V supply, the AD40xx ADCs consume as little as 14mW at 2MSPS with a minimum of 75MHz SCK rate in turbo-mode. The ADCs deliver ±1LSB INL maximum with no missing codes at 16-/18-Bits and 93dB/100.5dB SNR.
