Product Overviews
Digital Potentiometers
Microchip’s family of digital potentiometers offer a wide
range of options. These devices support the 6-bit through
8-bit applications. Offering both volatile and non-volatile
options, with digital interfaces from the simple Up/
Down interface to the standard SPI and I 2 C? interfaces.
These devices are offered in small packages such as
6-lead SC70 and 8-lead DFN for the single potentiometer
devices, 14-lead TSSOP and 16-lead QFN packages for the
dual potentiometer devices, and 20-lead TSSOP and QFN
packages for the quad potentiometer devices. Non-volatile
devices offer a Wiperlock? Technology feature, while volatile
devices will operate down to 1.8V. Resistances are offered
from 2.1?kΩ to 100 kΩ. Over 50 device configurations are
currently available.
The “Digital Potentiometer Design Guide” (Microchip
Document No. 22017), shows various application examples
of the digital potentiometer devices.
Digital-to-Analog Converters (DAC)
Microchip has a number of Digital-to-Analog Converters that
range from high performance 12-bit devices to cost effective
8-bit devices.
The MCP4725 is a single channel 12-bit DAC with non-
volatile memory (EEPROM). The user can store DAC input
code and configuration register bits into the EEPROM. This
non-volatile memory feature enables the device to hold
the DAC input code during power-off time allowing the DAC
output to be available immediately after power-up. This
feature is very useful when the DAC is used as a supporting
device for other device operations in systems. The
MCP4725 is availabe in a tiny SOT23-6 package.
The MCP4728 is a 12-bit DAC with four analog outputs. This
device also has non-volatile memory (EEPROM) for each DAC
channel. The user can select internal reference or V DD as
reference individually for each channel. The MCP4725 and
MCP4728 are available with I 2 C serial interface.
The MCP4821/2 family of 12-bit DACs combines high
performance with an internal reference voltage and SPI
interface. The MCP4921/2 family is similar and allows
for an external reference. These DAC devices provide
high accuracy and low noise, and are ideal for industrial
applications where calibration or compensation of signals
(such as temperature, pressure and humidity) is required.
The TC1320/1 family of DACs has 8- and 10-bit precision
that uses the 2-wire SMBus/I 2 C serial interface protocol.
