Overview
The ADS5295PFPR is a low-power, 12-bit, 100-MSPS, 8-channel analog-to-digital converter (ADC) produced by Texas Instruments. This device is designed for high channel count data acquisition systems, offering low power consumption and integration of multiple channels in a compact package. The ADS5295PFPR features serial low-voltage differential signaling (LVDS) outputs, which reduce the number of interface lines and enable high system integration. The device is available in a 12-mm × 12-mm QFP-80 package and is specified over the –40°C to +85°C operating temperature range.
