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.
