Description
General part information
ADS1224 Series
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. Data retrieval, self-calibration, and Standby mode are handled with a few simple waveforms. When only single conversions are needed, the ADS1224 can be quickly shut down (Standby mode) while idle between measurements to dramatically reduce the overall power consumption. Multiple ADS1224s can be connected together to create a synchronously sampling multichannel measurement system. The ADS1224 is designed to easily connect to microcontrollers, such as the MSP430.
