Page 5: Introduction
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. -
