12-bit 2-channel up to 50 MSPS current steering DAC

180TSMC_DAC_07 is a 12-bit 50 MSPS dual current steering DAC contains two DAC cores, reference current, bandgap, configuration register. Core DAC is based on current steering architecture and contains control logic, current source, switches array and reference voltage. There are two operation modes: with external reference current and internal reference current, which independent from voltage supply, temperature and dependent from process variations of resistor. DAC has a feature of adjusting output current. A segmented DAC architecture and Q2 random walk algorithm are used. DAC requires: 3.0 ÷ 3.6 V analog supply, 3.0 ÷ 3.6 V digital supply, differential input clock signal with duty cycle 45 ÷ 55%. 12-bit 50 MSPS dual current steering DAC supports standby mode.
