Dual 12-bit DAC in an 8-pin SOIC
It integrates two independent DACs with a buffered voltage output, each settling to within 1 LSB in 10 µs. The SPI-compatible serial interface controls both channels over a single data line, making it a compact fit for industrial control loops, programmable voltage references, and waveform generation where board area is tight.
Settling time and linearity budget
The 10 µs settling time to 1 LSB sets the maximum update rate at roughly 100 kHz for a full-scale step — fast enough for most closed-loop process control and audio-frequency signal generation. The ±2 LSB integral nonlinearity (INL) and ±0.5 LSB differential nonlinearity (DNL) define the analog output accuracy. For a 12-bit converter with a 5 V reference, ±2 LSB INL corresponds to a potential error of about 2.4 mV at the output; the ±0.5 LSB DNL guarantees monotonicity, which matters when the DAC drives a servo valve or a trim pot where a non-monotonic step would cause a control reversal.
Supply range and reference
The reference voltage is supplied externally — the output full-scale equals twice the reference voltage. This lets the designer set the output span independently of the supply, useful when the DAC drives an ADC with a different reference voltage or a sensor bridge that needs a precise 0-to-2.5 V range.
Production status and ordering
The 8-SOIC package ships in Tube form.
