Overview
The ADS1605IPAPT is a high-speed, high-precision 16-bit delta-sigma analog-to-digital converter (ADC) produced by Texas Instruments. This device is designed to operate at a data rate of 5 mega-samples per second (MSPS), with the option to double the data rate to 10 MSPS in 2X mode. It features a bandwidth of 2.45 MHz and a passband ripple of less than ±0.0025 dB. The ADS1605 is well-suited for demanding measurement applications in scientific instrumentation, automated test equipment, data acquisition, medical imaging, and vibration analysis.
