DESCRIPTION
The ADS1240 and ADS1241 are precision, wide dynamic range,
delta-sigma, Analog-to-Digital (A/D) converters with 24-bit resolution
operating from 2.7V to 5.25V power supplies. The delta-sigma A/D
converter provides up to 24 bits of no missing code performance and
effective resolution of 21 bits.
The input channels are multiplexed. Internal buffering can be
selected to provide very high input impedance for direct connection
to transducers or low-level voltage signals. Burnout current sources
are provided that allow for detection of an open or shorted sensor.
An 8-bit Digital-to-Analog (D/A) converter provides an offset cor-
rection with a range of 50% of the Full-Scale Range (FSR).
The Programmable Gain Amplifier (PGA) 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 modu-
lator and programmable Finite-Impulse Response (FIR) filter that
provides a simultaneous 50Hz and 60Hz notch. The reference input
is differential and can be used for ratiometric conversion.
The serial interface is SPI compatible. Up to eight bits of data
I/O are also provided that can be used for input or output. The
ADS1240 and ADS1241 are designed for high-resolution measure-
ment applications in smart transmitters, industrial process control,
weigh scales, chromatography, and portable instrumentation.
