ADS1174IPAPT

The ADS1174IPAPT is a multiple delta-sigma (ΔΣ) Analog-to-digital Converter (ADC) with data rates up to 52k samples-per-second (SPS) which allow synchronous sampling of four and 8-channel. This device uses identical packages and is also compatible with the high-performance 24-bit ADC permitting drop-in upgrades. The delta-sigma architecture offers near ideal 16-bit AC performance combined with 0.005dB pass-band ripple and linear phase response. The high-order, chopper-stabilized modulator achieves very low drift. The on-chip finite impulse response (FIR) filter provides usable signal bandwidth up to 90% of the Nyquist rate with 100dB of stop band attenuation while suppressing modulator and signal out-of-band noise. Two operating modes allow for optimization of speed and power - high-speed mode and low-power mode. A SYNC input control pin allows the device conversions to be started and synchronized to an external event.
