DESCRIPTION
The ADS1203 is a delta-sigma (ΔΣ) 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, and industrial process control. The
ADS1203 is available in TSSOP-8 and QFN-16 (3x3)
packages.
