16-channel, 24-bit, 1MSPS delta-sigma ADC with high voltage inputs (±10V) using a 5V supply

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.
