DESCRIPTION
The ADS1203 is a delta-sigma (
Σ
) modulator with a
95dB dynamic range, operating from a single +5V
supply. The differential inputs are ideal for direct
connection to transducers or low-level signals. With the
appropriate digital filter and modulator rate, the device
can be used to achieve 16-bit analog-to-digital (A/D)
conversion with no missing codes. An effective
resolution of 14 bits or SNR of 85dB (typical) can be
maintained with a digital filter bandwidth of 40kHz at a
modulator rate of 10MHz. The ADS1203 is designed for
use in medium- to high-resolution measurement
applications including current measurements, smart
transmitters, industrial process control, weigh scales,
chromatography, and portable instrumentation. It is
available in an 8-lead TSSOP package. A 16-pin QFN
(3x3) package will be available soon.
