DESCRIPTION
The ADS1212 and ADS1213 are precision, wide
dynamic range, delta-sigma analog-to-digital 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 sig-
nals. The delta-sigma architecture is used for wide
dynamic range and to guarantee 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 provid-
ing 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 trans-
mitters, industrial process control, weigh scales, chro-
matography and portable instrumentation. Both con-
verters include a flexible synchronous serial interface
which 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 18-pin DIP and 18-lead SOIC pack-
ages. The ADS1213 includes a 4 channel input multi-
plexer and is available in 24-pin DIP, 24-lead SOIC,
and 28-lead SSOP packages.
