16-Bit, 570 kSPS, Unipolar CMOS Successive Approximation ADC

The AD7650 is a low cost, 16-bit, 570 kSPS, unipolar CMOS Successive Approximation ADC featuring 15-bits No Missing Codes. This model was developed to compete against ADCs with similar performance but at a higher sampling frequency. The AD7650 is an excellent, low cost complement to our previously introduced, high-performance 16-bit ADCs (AD7664 and AD7665).

Typical AC specifications are 86 dB SINAD and -98 THD @ 45 kHz. DC performance is ±6 LSB INL and 15-bits of no missing codes. Maximum power dissipation is 115 mW @500 kSPS and typically 21 µW @100 SPS. The AD7650 features differential inputs with a 0 V to 2.5 V input range. This model is available in the 48-lead LQFP or, for applications where board space is critical, the chip scale 48-lead LFCSP. The AD7650 is the first PulSAR ADC to feature this new package.
