ADC161S626CIMME/NOPB

Product Summary

The ADC161S626CIMME/NOPB is a 16-bit successive-approximation register (SAR) Analog-to-Digital converter (ADC) with a maximum sampling rate of 250 kSPS. The ADC161S626CIMME/NOPB has a minimum signal span accuracy of ± 0.003% over the temperate range of -40℃ to +85℃. The converter features a differential analog input with an excellent common-mode signal rejection ratio of 85 dB, making the ADC161S626CIMME/NOPB suitable for noisy environments. The ADC161S626CIMME/NOPB 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. The performance of the ADC161S626CIMME/NOPB is guaranteed over temperature at clock rates of 1 MHz to 5 MHz and reference voltages of +2.5V to +5.5V. The ADC161S626CIMME/NOPB is available in a small 10-lead MSOP package. The high accuracy, differential input, low power consumption, and small size make the ADC161S626CIMME/NOPB ideal for direct connection to bridge sensors and transducers in battery operated systems or remote data acquisition applications.
