ADS1211U Description

Short technical summary and product information.

The ADS1211U is a precision, wide dynamic range, delta-sigma analog-to-digital converter from Texas Instruments. It features 24-bit resolution and 22-bit no missing code performance. The device includes a 4-channel multiplexer, programmable gain amplifier (PGA), and a flexible SPI-compatible serial interface with 2-wire mode. It supports both internal and external voltage references.

 

With an effective resolution of 23 bits at 10 Hz and 20 bits at 1000 Hz, the ADS1211U delivers high accuracy for low-speed measurement applications. The typical sampling rate is 16 kSPS. The differential inputs are ideal for direct connection to transducers or low-level voltage signals. The device also features on-chip self-calibration.

 

The ADS1211U is supplied in a 24-SOIC surface mount package and operates over a temperature range of -40°C to 85°C from a single 5V supply. It is commonly used in industrial process control, instrumentation, blood analysis, smart transmitters, portable instruments, weigh scales, and pressure transducers.
