The ADS125H18 is a high voltage input, multiplexed 8/16-Channel, 24 bit, delta-sigma (ΔΣ), analog-to-digital converter (ADC) with data rates up to 1MSPS and is configurable to accept up to 8 fully differential analog inputs or up to 16 single-ended analog inputs. Each input comprises a high-impedance voltage divider with integrated precision matched resistors to scale down the input voltage to the input range of the ADC. The device offers an excellent combination of ac performance and dc precision with low power consumption.
The ADS125H18 is equipped with a channel auto-sequencer and a FIFO (first-in, first-out) buffer. The power-scalable architecture provides four speed modes to optimize data rate, resolution, and power consumption.
The small 5mm × 5mm VQFN package is designed for limited space applications. The device is fully specified for operation over the –40°C to +125°C temperature range.
