Corebai Microelectronics CBM76AD06

This device is a 16-bit, 8-channel synchronous sampling analog-to-digital data acquisition system. Each device integrates analog input clamp protection, a second-order anti-aliasing filter, a sample-and-hold amplifier, a 16-bit charge redistribution SAR ADC, a flexible digital filter, a 2.5V voltage reference, reference buffer, and high-speed serial and parallel interfaces. The device operates from a single 5V supply and can handle ±10V and ±5V true bipolar input signals, with all channels capable of sampling at throughput rates up to 200kSPS. The input clamp protection circuit can withstand voltages up to ±16.5V. The analog input impedance is 1 MΩ regardless of the sampling frequency. Operating from a single supply with on-chip filtering and high input impedance, the device eliminates the need for a driver op-amp and external bipolar power supplies. The anti-aliasing filter has a 3dB cutoff frequency of 22 kHz; at a sampling rate of 200 kSPS, it provides 40dB anti-aliasing rejection. The flexible digital filter is pin-driven and can improve SNR while reducing the 3dB bandwidth.
