DESCRIPTION
The ADS1218 is a precision, wide dynamic range, delta-sigma, Analog-to-
Digital (A/D) converter with 24-bit resolution and FLASH memory operating
from 2.7V to 5.25V supplies. The delta-sigma, A/D converter provides up to
24 bits of no missing code performance and effective resolution of 22 bits.
The eight input channels are multiplexed. Internal buffering can be selected
to provide a very high input impedance for direct connection to transducers
or low-level voltage signals. Burn out current sources are provided that allow
for the detection of an open or shorted sensor. An 8-bit Digital-to-Analog (D/
A) converter provides an offset correction with a range of 50% of the FSR
(Full-Scale Range).
The PGA (Programmable Gain Amplifier) provides selectable gains of 1 to
128 with an effective resolution of 19 bits at a gain of 128. The A/D
conversion is accomplished with a second-order delta-sigma modulator and
programmable sinc filter. The reference input is differential and can be used
for ratiometric conversion. The on-board current DACs (Digital-to-Analog
Converters) operate independently with the maximum current set by an
external resistor.
The serial interface is SPI compatible. Eight bits of digital I/O are also provided
that can be used for input or output. The ADS1218 is designed for high-resolution
measurement applications in smart transmitters, industrial process control, weight
scales, chromatography, and portable instrumentation.
