GF 55nm LPe, 8-ch, 12-bit 1MSPS Low-power SAR ADC

Overview

The L7GAD12B001M IP is a successive– approximation-register (SAR) type analog-to-digital converter (ADC), which consists of an 8-channel input MUX, a digital-to-analog converter (DAC), a comparator, and control logic including a SAR. The L7GAD12B001M, operating with 3.3V analog power supply and 1.2V digital power supply, consumes 3.63mW power at 1-MS/s sampling rate.
