The AD7661 is a 16-bit, 100 kSPS, charge redistribution SAR analog-to-digital converter that operates from a single 5 V power supply. The part contains a high speed 16-bit sampling ADC, an internal conversion clock, internal reference, error correction circuits, and both serial and parallel system interface ports. The AD7661 is hardware factory-calibrated and comprehensively tested to ensure ac parameters such as signal-to-noise ratio (SNR) and total harmonic distortion (THD), in addition to the more traditional dc parameters of gain, offset, and linearity.The AD7661 is available in a 48-lead LQFP and a tiny 48-lead LFCSP with operation specified from –40°C to +85°C.PRODUCT HIGHLIGHTS Fast Throughput. The AD7661 is a 100 kSPS, charge redistribution, 16-bit SAR ADC with internal error correction circuitry. Superior INL. The AD7661 has a maximum integral nonlinearity of 2.5 LSB with no missing 16-bit codes. Internal Reference. The AD7661 has an internal reference with a typical temperature drift of 3 ppm/°C. Single-Supply Operation. The AD7661 operates from a single 5 V supply. Its power dissipation decreases with throughput. Serial or Parallel Interface. Versatile parallel or 2-wire serial interface arrangement is compatible with both 3 V and 5 V logic.
