a fraction (~ <1/4) of an LSB to ensure monotonic behavior
when stepping through codes.
The input bias current of an op amp also generates an offset at
the voltage output as a result of the bias current flowing in the
feedback resistor, RFB. Most op amps have input bias currents low
enough to prevent any significant errors in 12-bit applications.
Common-mode rejection of the op amp is important in voltage
switching circuits since it produces a code-dependent error at
the voltage output of the circuit. Most op amps have adequate
common-mode rejection at an 8-, 10-, or 12-bit resolution.
Provided the DAC switches are driven from true wideband low
impedance sources (VIN and AGND), they settle quickly.
Consequently, the slew rate and settling time of a voltage switching
DAC circuit is determined largely by the output op amp.
To obtain minimum settling time in this configuration, it is
important to minimize capacitance at the VREF of the DAC. This
is done by using low input capacitance buffer amplifiers and
careful board design. Most single-supply circuits include ground as
part of the analog signal range, which in turn requires an amplifier
that can handle rail-to-rail signals,. There is a large range of
single-supply amplifiers available from Analog Devices.
