The AD7654 is a 16-bit, 500 kSPS PulSAR® dual, 2-channel, simultaneous sampling ADC. It features a 16-bit resolution with no missing codes, a throughput of 500 kSPS (normal mode) and 444 kSPS (impulse mode). Its INL is ±3.5 LSB max (±0.0053% of full scale), SNR is 89 dB typical @ 100 kHz, and THD is -100 dB @ +100 kHz. The AD7654 has an analog input voltage range of 0 V to 5 V, no pipeline delay, and a parallel and serial 5 V/3 V interface that is compatible with SPI®/QSPI™/MICROWIRE™/DSP. It operates from a single 5 V supply, and its typical power dissipation is 120 mW and 2.6 mW @ 10 kSPS. The AD7654 is available in 48-lead low profile quad flat package (LQFP) and 48-lead lead frame chip scale package (LFCSP), and is low cost.
