Overview
The ADS1259QPWRQ1 is a high-performance, 24-bit analog-to-digital converter (ADC) designed by Texas Instruments. This device is specifically tailored for demanding applications such as industrial process control, precision instrumentation, and automotive systems. It offers high-resolution output data at sample rates ranging from 10 SPS to 14.4 kSPS. The ADS1259QPWRQ1 integrates a low-drift, low-noise 2.5V reference and features a SPI-compatible interface for data and control communication. The device is known for its low power consumption, dissipating only 13 mW during operation and less than 25 μW in power-down mode. It is available in a TSSOP-20 package and is fully specified from –40°C to +125°C.
