ADS4126 - Ultralow-Power ADC

Download the ADS4126 datasheet PDF. This datasheet also covers the ADS4149 variant, as both devices belong to the same ultralow-power adc family and are provided as variant models within a single manufacturer datasheet.

General Description

The ADS412x/4x are a family of 12-bit/14-bit analog-to-digital converters (ADCs) with sampling rates up to 250MSPS.

These devices use innovative design techniques to achieve high dynamic performance, while consuming extremely low power at 1.8V supply.
