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, R
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 (V
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 V
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.
