Description

Specifications:
1pcs AD7616BSTZ-RL LQFP-80 16-channel DAS built-in 16-bit synchronous sampling ADC Chip
AD7616 is a 16-bit DAS that supports dual simultaneous sampling of 16 channels. AD7616 is powered by a single 5 V power supply and can handle true bipolar input signals of ±10 V, ±5 V and ±2.5 V. At the same time, each pair of channels can sample at a throughput rate of up to 1 MSPS and 90.5 dB SNR. Using the on-chip oversampling mode can achieve higher SNR performance (when the oversampling rate (OSR) is 2, the SNR is 92 dB).
The input clamp protection circuit can withstand voltages up to ±21 V. Regardless of the sampling frequency, the analog input impedance of AD7616 is 1 MÙ. It adopts a single power supply mode, with on-chip filtering and high input impedance, so there is no need to drive operational amplifiers and external bipolar power supplies.
The devices have built-in analog input clamp protection, a dual 16-bit charge redistribution SAR analog-to-digital converter (ADC), a flexible digital filter, 2.5 V reference voltage source and reference voltage buffer, and high-speed serial and parallel interface.
