:The ADS8661IPWR is a high-performance, single-channel, 12-bit, 1.25-MHz sampling analog-to-digital converter (ADC) with programmable input ranges of ±12, ±10, ±6, ±5, and ±2.5 volts on a +5 volt supply, packaged in a 16-lead, thin, small-outline package (TSSOP) that operates from -40°C to 125°C. It has low power consumption and low distortion features, allowing its use in both high-end and low power systems. The ADS8661IPWR also has an on-chip sample-and-hold amplifier for improved signal performance. Additionally, the low-noise performance means it can be used in applications requiring high accuracy measurements.
