ADC161S626
ADC161S626 is MicroPower ADC manufactured by National Semiconductor.
Description
The ADC161S626 is a 16-bit successive-approximation register (SAR) Analog-to-Digital converter (ADC) with a maximum sampling rate of 250 k SPS. 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 mon-mode signal rejection ratio of 85 d B, making the ADC161S626 suitable for noisy environments. The ADC161S626 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 plement and is SPI™ patible. The performance of the ADC161S626 is guaranteed over temperature at clock rates of 1 MHz to 5 MHz and reference voltages of +2.5V to +5.5V. The ADC161S626 is available in a small 10-lead MSOP package. The high accuracy, differential input, low power consumption, and small size make the ADC161S626 ideal for direct connection to bridge sensors and transducers in battery operated systems or remote data acquisition applications.
