DESCRIPTIONThe ADS1217 is a precision, wide dynamic range, delta-
sigma, Analog-to-Digital (A/D) converter with 24-bit resolu-
tion 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.
Burnout current sources are provided that allow for the
detection of an open or shorted sensor. An 8-bit Digital-to-
Analog Converter (DAC) 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 2nd-order,
delta-sigma modulator and programmable sinc filter. The
reference input is differential and can be used for ratiometric
measurements. The onboard current DACs operate indepen-
dently 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
ADS1217 is designed for high-resolution measurement appli-
cations in smart transmitters, industrial process control, weigh
scales, chromatography, and portable instrumentation.
