The 16-bit charge-redistribution SAR analog-to-digital converter samples fully differential inputs at up to 500 kSPS. It operates from a single 5 V supply and provides internal conversion clocking, error correction, and serial or parallel interface ports. The converter supports a ±2.5 V differential input range with no pipeline delay. Typical dynamic performance includes 94 dB signal-to-noise-plus-distortion and −110 dB total harmonic distortion at 45 kHz. Package options include 48-lead LQFP and 48-lead LFCSP formats.
