ADS9128中文资料16-bit, 10MSPS SAR ADC w/ ADC Driver and Reference Driver in 5mm x 5mm QFN数据手册TI规格书

描述 Description

The ADS912x is a family of 16-bit, high-speed, analog-to-digital converters (ADCs) with an integrated driver for the ADC inputs. The integrated ADC driver simplifies the signal chain, reduces power consumption for precision applications, and supports high-frequency signals beyond 1MHz. By not requiring an external decoupling capacitor, the integrated ADC reference buffer is optimized for wide bandwidth applications.

The ADS912x uses a serial LVDS (SLVDS) data interface that enables high-speed digital communication while minimizing digital switching noise. Read the ADC data using separate SLVDS outputs per ADC channel or one SLVDS output for both ADC channels.
