Description

The ADS1224 is a 4-channel, 24-bit, delta-sigma analog- to-digital (A/D) converter. It offers excellent performance and low power in a TSSOP-20 package. The ADS1224 is well-suited for demanding, high-resolution measurements, especially in portable systems and other space-saving and power-constrained applications.

A delta-sigma (ΔΣ) modulator and digital filter form the basis of the A/D converter. The analog modulator has a ±5V differential input range. An input multiplexer (MUX) is used to select between four separate differential input channels. A buffer can be selected to increase the input impedance of the measurement.

A simple, 2-wire serial interface provides all the necessary control.
