ADS1211E Description

Short technical summary and product information.

The ADS1211E is a 24-bit Sigma-Delta analog-to-digital converter (ADC) manufactured by Texas Instruments. It offers 4 differential input channels, a maximum sampling rate of 16 kS/s, and a programmable gain amplifier (PGA). The ADC uses a MUX-PGA-ADC configuration and supports both external and internal voltage references.

 

The device operates from a single 5V analog and digital supply. It communicates via a serial peripheral interface (SPI) for data transfer. The Sigma-Delta architecture provides high-resolution conversion with excellent noise performance.

 

The ADS1211E is housed in a 28-SSOP (0.209", 5.30mm Width) surface-mount package. It is specified for operation over the -40°C to +85°C temperature range. The device is shipped in tape and reel packaging suitable for automated assembly.
