DAC8801
SLAS403B – NOVEMBER 2004 – REVISED FEBRUARY 2007
The DAC8801 is a single channel current output, 16-bit digital-to-analog converter (DAC). The architecture,
illustrated in Figure 17, is an R-2R ladder configuration with the three MSBs segmented. Each 2R leg of the
ladder is either switched to GND or the IOUT terminal. The IOUT terminal of the DAC is held at a virtual GND
potential by the use of an external I/V converter op amp. The R-2R ladder is connected to an external reference
input VREF that determines the DAC full-scale current. The R-2R ladder presents a code independent load
impedance to the external reference of 5 k
Ω± 25%. The external reference voltage can vary in a range of -10 V
to 10 V, thus providing bipolar IOUT current operation. By using an external I/V converter and the DAC8801 RFB
resistor, output voltage ranges of -VREF to VREF can be generated.
When using an external I/V converter and the DAC8801 RFB resistor, the DAC output voltage is given by
Equation 1:
Figure 17. Equivalent R-2R DAC Circuit
Each DAC code determines the 2R leg switch position to either GND or IOUT. Because the DAC output
impedance as seen looking into the IOUT terminal changes versus code, the external I/V converter noise gain will
also change. Because of this, the external I/V converter op amp must have a sufficiently low offset voltage such
that the amplifier offset is not modulated by the DAC IOUT terminal impedance change. External op amps with
large offset voltages can produce INL errors in the transfer function of the DAC8801 due to offset modulation
versus DAC code. For best linearity performance of the DAC8801, an op amp (OPA277) as shown in Figure 18
is recommended. This circuit allows VREF to swing from -10V to +10V.
