12-bit 1-channel up to 1 MSPS R/2R DAC

Overview

090TSMC_DAC_02 is a 12-bit 1- channel R/2R DAC with sampling rate up to 1 MSPS. The DAC contains four main blocks: reference voltage source, bias voltage source, DAC core and control digital module. DAC core consist of the R/2R matrix and output operational class AB amplifier. Digital control register adj<15:4> sets optimal mode. It corrects output buffers current, common mode and output signal swing. DAC requires 1.62 ÷ 1.98 V (port Vdd18) analog supply voltage and 0.9 ÷ 1.1 V (port Vdd) digital supply voltage.
