The ADS1225 and ADS1226 are 24-bit delta-sigma analog-to-digital (A/D) converters. They offer excellent performance, ease-of-use, and low power in a small 4mm × 4mm QFN package and are well-suited for demanding high-resolution measurements, especially in portable and other space-saving and power-constrained applications.
The ADS1225 and ADS1226 convert on command using a dedicated START pin. Simply pulse this pin to initiate a conversion. Data is read in a single cycle for retrieval over a 2-wire serial interface that easily connects to popular microcontrollers like the MSP430. After the conversion completes, the ADS1225 and ADS1226 automatically shuts down all circuitry.
Internal features include a two-channel multiplexer (ADS1226), selectable input buffer, temperature sensor, and oscillator.
