DESCRIPTION
The ADS1212 and ADS1213 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 transducers or low-level voltage signals. The delta-sigma architecture is used for wide dynamic range and to ensure 22 bits of
no-missing-code performance. An effective resolution of 20
bits is achieved through the use of a very low-noise input
amplifier at conversion rates up to 10Hz. Effective resolutions of 16 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 ADS1212 and ADS1213 are designed for high-resolution
measurement applications in smart transmitters, industrial
process control, weigh scales, chromatography and portable
instrumentation. Both converters include a flexible synchronous serial interface that is SPI compatible and also offers a
two-wire control mode for low-cost isolation.
The ADS1212 is a single channel converter and is offered in
both DIP-18 and SO-18 packages. The ADS1213 includes a
4-channel input multiplexer and is available in DIP-24,
SO-24, and SSOP-28 packages.
APPLICATIONS
● INDUSTRIAL PROCESS CONTROL
● INSTRUMENTATION
