The ADS1675 is a high-speed, high-precision analog-to-digital converter (ADC). Using an advanced delta-sigma () architecture, it operates at speeds up to 4MSPS with outstanding ac performance and dc accuracy.

The ADS1675 ADC is comprised of a low-drift modulator with out-of-range detection and a dual-path programmable digital filter. The dual filter path allows the user to select between two post-processing filters: Low-Latency or Wide-Bandwidth. The Low-Latency filter settles quickly (as fast as 2.65µs) for applications with large instantaneous changes, such as a multiplexer. The Wide-Bandwidth path provides an optimized frequency response for ac measurements with a passband ripple of less than ±0.00002dB, stop band attenuation of 86dB, and a bandwidth of 1.7MHz.

The device offers two speed modes with distinct interface, resolution, and feature set. In the high-speed mode the device can be set to operate at either 4MSPS or 2MSPS. In the low-speed mode, it can be set to operate at either 1MSPS, 500KSPS, 250KSPS or 125KSPS.Read more
