DESCRIPTIONThe ADS1210 and ADS1211 are precision, wide dynamic
range, delta-sigma Analog-to-Digital (A/D) converters with
24-bit resolution operating from a single +5V supply. The
differential inputs are ideal for direct connection to transduc-
ers or low-level voltage signals. The delta-sigma architec-
ture is used for wide dynamic range and to ensure 22 bits
of no-missing-code performance. An effective resolution of
23 bits is achieved through the use of a very low-noise input
amplifier at conversion rates up to 10Hz. Effective resolu-
tions of 20 bits can be maintained up to a sample rate of
1kHz through the use of the unique Turbo modulator mode
of operation. The dynamic range of the converters is further
increased by providing a low-noise programmable gain
amplifier with a gain range of 1 to 16 in binary steps.
The ADS1210 and ADS1211 are designed for high resolution
measurement applications in smart transmitters, industrial
process control, weigh scales, chromatography, and portable
instrumentation. Both converters include a flexible synchro-
nous serial interface that is SPI-compatible and also offers a
two-wire control mode for low cost isolation.
The ADS1210 is a single-channel converter and is offered in
both 18-pin DIP and 18-lead SOIC packages. The ADS1211
includes a 4-channel input multiplexer and is available in 24-
pin DIP, 24-lead SOIC, and 28-lead SSOP packages.
