DESCRIPTION
The ADS1259 is a high-linearity, low-drift, 24-bit,

High Performance:
instrumentation, and other exacting applications.
Combined with a signal amplifier (such as the

– Offset Drift: 0.05μV/°C
The converter uses a fourth-order, inherently stable,

Dissipating only 13mW in operation, the ADS1259
can be powered down, dissipating less than 25
μW.
The ADS1259 is offered in a TSSOP-20 package and
is fully specified from
–40°C to +105°C.
