National Semiconductor ADC161S626 MicroPower ADC

National Semiconductor's 16-bit successive-approximation register (SAR) analog-to-digital converter


National Semiconductor's ADC161S626 is a 16-bit successive-approximation register (SAR) analog-to-digital converter (ADC) with a maximum sampling rate of 250kSPS. The ADC161S626 has a minimum signal span accuracy of ±0.003% over the temperate range of −40°C to +85°C. The converter features a differential analog input with an excellent common-mode signal rejection ratio of 85dB, making the ADC161S626 suitable for noisy environments. It operates with a single analog supply (VA) and a separate digital input/output (VIO) supply. VA can range from +4.5V to +5.5V and VIO can range from +2.7V to +5.5V. This allows a system designer to maximize performance and minimize power consumption by operating the analog portion of the ADC at a VA of +5V while interfacing with a +3.3V controller. The serial data output is binary 2's complement and is SPI™ compatible.
