Overview
The Texas Instruments ADC161S626CIMM/NOPB is a 16-bit successive-approximation register (SAR) Analog-to-Digital Converter (ADC) designed for high accuracy and low power consumption. This ADC features a maximum sampling rate of 250 kSPS and is ideal for applications requiring precise analog-to-digital conversion in noisy environments. The device operates with a single analog supply (V_A) ranging from 4.5 V to 5.5 V and a separate digital input/output supply (V_IO) ranging from 2.7 V to 5.5 V, allowing for flexible system design. The ADC161S626CIMM/NOPB is available in a small 10-lead VSSOP package, making it suitable for battery-operated systems and remote data acquisition applications.
