• Single-Cycle Conversion

ADS1000 operates from a single power supply

ranging from 2.7V to 5.5V.

• Programmable Gain Amplifier

Gain = 1, 2, 4, or 8

The ADS1000 performs conversions at a rate of 128

measured with high resolution. In single-conversion

• Pin- and Software-Compatible with 16-Bit

mode, the ADS1000 automatically powers down after
