Alert me about changes<br/>to this product

Alert Icon   NRND: This product is not recommended for new designs. However, the device, tool, or software continues to be in production to support existing customers. TI does not recommend using this part in a new design. TI encourages designers to consider alternative products for new designs.

Replaced By:

  • ADS6122 The device has the SAME FUNCTIONALITY as the compared device, but is not pin-for-pin equivalent and may not be parametrically equivalent.TI encourages design engineers consider the ADS6122 over the ADS5221. The ADS6122 consumes the same power, offers higher performance across all input frequencies and comes in a smaller package than the ADS5221.

Description

The ADS5221 is a pipeline, CMOS Analog-to-Digital Converter (ADC) that operates from a single +3.3V power supply. This converter provides excellent performance with a single-ended input and can be operated with a differential input for added spurious performance. This high-performance converter includes a 12-bit quantizer, high bandwidth track-and-hold, and a high accuracy internal reference; it also allows for the user to disable the internal reference and utilize external references, providing excellent gain and offset matching in multi-channel applications or in applications where full-scale range adjustment is required.

The ADS5221 employs digital error correction techniques to enable excellent differential linearity for demanding imaging applications.
