The AD7616 is a 16-bit, DAS that supports dual simultaneous sampling of 16 channels. The AD7616 operates from a single 5 V supply and can accommodate ±10 V, ±5 V, and ±2.5 V true bipolar input signals while sampling at throughput rates up to 1 MSPS per channel pair with 90.5 dB SNR. Higher SNR performance can be achieved with the on-chip oversampling mode (92 dB for an oversampling ratio (OSR) of 2). The input clamp protection circuitry can tolerate voltages up to ±21 V. The AD7616 has 1 MÙ analog input impedance, regardless of sampling frequency. The single-supply operation, on-chip filtering, and high input impedance eliminate the need for driver op amps and external bipolar supplies. The device contains analog input clamp protection, a dual, 16-bit charge redistribution SAR analog-to-digital converter (ADC), a flexible digital filter, a 2.5 V reference and reference buffer, and high speed serial and parallel interfaces. The AD7616 is serial peripheral interface (SPI)/QSPI™/DSP/ MICROWIRE compatible Applications * Power line monitoring * Protective relays * Multiphase motor control * Instrumentation and control systems * Data acquisition systems (DASs) * 16-channel, dual, simultaneously sampled inputs * Independently selectable channel input ranges * True bipolar: ±10 V, ±5 V, ±2.5 V * Single 5 V analog supply and 2.3 V to 3.6 V VDRIVE supply * Fully integrated data acquisition solution * Analog input clamp protection * Input buffer with 1 MΩ analog input impedance * First-order antialiasing analog filter * On-chip accurate reference and reference buffer * Dual 16-bit successive approximation register (SAR) ADC * Throughput rate: 2 × 1 MSPS * Oversampling capability with digital filter * Flexible sequencer with burst mode https://elecena.pl/product/14872017/16-channel-das-with-16-bit-bipolar-input-dual-simultaneous-sampling-adc 2018-05-21 https://elecena.pl/product/14872017/16-channel-das-with-16-bit-bipolar-input-dual-simultaneous-sampling-adc 2025-01-17
