Introduction
The Texas Instruments ADC161S626EVM evaluation module (EVM) helps designers evaluate the
operation and performance of the ADC161S626. The ADC161S626 is a 16-bit, 50kSPS to 250kSPS
sampling Analog-to-Digital (A/D) converter. The converter uses a successive-approximation register (SAR)
architecture, based upon capacitive redistribution and containing an inherent sample-and-hold function.
The differential nature of the analog inputs is maintained from the internal sample-and-hold circuits
throughout the A/D converter to provide excellent common-mode signal rejection.
The EVM contains an LMP8350 and an ADC161S626. The LMP8350 is an ultra-low distortion, fully-
differential amplifier designed for driving high-performance precision analog-to-digital converters (ADC).
The user can use the LMP8350 to drive the ADC, or test the performance of ADC161S626 directly. The
evaluation board communicates with the MSP430’s Launch-Pad through the SPI interface.
