Power Amplifier Control
Multistage power amplifier designs require a large number of
setpoints in the operation and control of the output stage. The
AD539x are ideal for these applications because of their small
size (LFCSP) and the integration of 8 and 16 channels, offering
12- and 14-bit resolution. Figure 45 shows a typical transmitter
architecture, in which the AD539x DACs can be used in the
following control circuits: IBIAS control, average power control
(APC), peak power control (PPC), transmit gain control (TGC),
and audio level control (ALC). DACs are also required for
variable voltage attenuators, phase shifter control, and dc-
setpoint control in the overall amplifier design.

Process Control Applications
The AD539x-5 family is ideal for process control applications
because it offers a combination of 8 and 16 channels and 12-bit
and 14-bit resolution. These applications generally require
output voltage ranges of 0 V to 5 V ± 5 V, 0 V to 10 V ± 10 V,
and current sink and source functions. The AD539x-5 products
operate from a single 5 V supply and, therefore, require external
signal conditioning to achieve the output ranges described here.
Figure 46 shows configurations to achieve these output ranges.
The key advantages of using AD539x-5 products in these
applications are small package size, pin compatibility with the
ability to upgrade from 12 to 14 bits, integrated on-chip 2.5 V
reference with 10 ppm/°C maximum temperature coefficient,
and excellent accuracy specifications. The AD539x-5 family
contains an offset and gain register for each channel, so users
can perform system-level calibration on a per-channel basis.

Optical Transceivers
The AD539x-3 family of products are ideally suited to optical
transceiver applications. In 300-pin MSA applications, for
example, digital-to-analog converters are required to control the
laser power, APD bias, and modulator amplitude. Diagnostic
information is required as analog outputs from the module. The
AD539x-3 products offer a combination of 8/16 channels, a
resolution of 12/14 bits in a 64-lead LFCSP, and operate from a
supply voltage of 2.7 V to 5.5 V supply with internal reference.
The AD539x-3 parts also feature I2C-compatible and SPI inter-
faces, making them ideal components for use in these applications.
Figure 47 shows a typical configuration in an optical transceiver
application.
