DESCRIPTION
The ADS1225 and ADS1226 are 24-bit delta-sigma
analog-to-digital
(A/D)
excellent performance, ease-of-use, and low power
in a small 4mm
×
4mm QFN package and are
well-suited
for
demanding
measurements, especially in portable and other
space-saving and power-constrained applications.

offer
high-resolution
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
MSP430.
After

Internal features include a two-channel multiplexer
(ADS1226),

sensor, and oscillator. The full-scale range is defined
by the external voltage reference with support
provided for up to a 5V differential input signal. Two

The ADS1225/6 supports 2.7 to 5.5V analog and
digital supplies. Power consumption is 1mW while
converting with 3V supplies. The ADS1225 and
ADS1226 are fully specified over an extended
industrial temperature range of –40
°
C to +105
