The remaining two amplifiers can be used as low voltage
microphone preamplifiers. A single AD8614 can be used as a
stand-alone microphone preamplifier. Figure 29 shows this
implementation.

SPICE Model Availability
The SPICE model for the AD8614/AD8644 amplifier is available
and can be downloaded from the Analog Devices’ web site at
http://www.analog.com
. The macro-model accurately simulates
a number of AD8614/AD8644 parameters, including offset volt-
age, input common-mode range, and rail-to-rail output swing.
The output voltage versus output current characteristic of the
macro-model is identical to the actual AD8614/AD8644 perfor-
mance, which is a critical feature with a rail-to-rail amplifier model.
The model also accurately simulates many ac effects, such as gain
bandwidth product, phase margin, input voltage noise, CMRR and
PSRR versus frequency, and transient response. Its high degree of
model accuracy makes the AD8614/AD8644 macro-model one of
the most reliable and true-to-life models available for any amplifier.
