DESCRIPTION
The ADS8329 is a low-power, 16-bit, 1-MSPS
analog-to-digital converter (ADC) with a unipolar
input. The device includes a 16-bit capacitor-based
SAR ADC with inherent sample-and-hold.
The ADS8330 is based on the same core and
includes a 2-to-1 input MUX with programmable
option of TAG bit output. Both the ADS8329 and
ADS8330 offer a high-speed, wide voltage serial
interface and are capable of chain mode operation
when multiple converters are used.
These converters are available in 4 × 4 QFN and
16-pin TSSOP packages, and are fully specified for
operation over the industrial –40°C to +85°C
temperature range.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.

(1) Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under recommended operating
conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
