Data Acquisition - Digital to Analog Converters (DAC) have become an ever more popular way of transferring digital signals into analog form. The LTC2632CTS8-LZ12#TRPBF is a 12-bit Digital to Analog Converter (DAC) that is well suited for industrial, medical, communication and consumer applications.

General Description

The LTC2632CTS8-LZ12#TRPBF is a low power, low noise, 12-bit digital-to-analog converter (DAC) with a buffered differential voltage output. The DAC operates from a single 2.7 V to 5.25 V supply and provides an unbuffered 0 V to 3 V output range. The LTC2632CTS8-LZ12#TRPBF includes a 2.5 V reference and an internal reference buffer for driving an external reference voltage. The output scale can be adjusted via an internal integrated scaler, which permits the user to independently adjust the full scale as a percentage of the reference voltage.

The LTC2632CTS8-LZ12#TRPBF has a full-scale span that is adjustable from 0 V to 3 V. It also features a power-down mode at 1 μA. It has a power-on reset circuitry that is used to ensure a known state upon device power up.

External Reference Voltage

The LTC2632CTS8-LZ12#TRPBF includes an internal 2.5 V reference. This provides a simple, cost-effective solution to providing a standard reference voltage for the DAC. A buffered version of this reference voltage is available at the REFBUF pin (pin 5), and can be used to drive an external reference if needed.

It is also possible to interface the LTC2632CTS8-LZ12#TRPBF to an external reference voltage. An external reference of 0 V to 1.2 V can be directly applied to the REF pin (pin 4). This allows the flexibility to select a different reference voltage than the typical 2.5 V device option.

Current-Mode Output

The LTC2632CTS8-LZ12#TRPBF features a current-mode output, which is ideal for analog filtering, and offers the lowest output noise and distortion. The device features an integrated output driver that can source or sink up to 20 mA. The output driver is capable of driving a variety of loads and can be used to drive ac or dc current into either single-ended (grounded load) or differential loads.

Power Management

The LTC2632CTS8-LZ12#TRPBF has an integrated power management system that is used to reduce power consumption when the device is idle. The device can be operated in a low-power standby mode at 1 μA and still maintain full accuracy. The power-down feature enables the user to select the amount of time required to ramp up to operating level or to reach full accuracy after devices have been powered up.

Applications

Some of the applications of the LTC2632CTS8-LZ12#TRPBF includes data acquisition systems, automotive instrumentation and infotainment systems, medical imaging, communications, high-end audio and professional audio systems, and home appliance control systems. It is also suitable for any application requiring a high-precision Digital to Analog conversion.

Working Principle

The working principle of the LTC2632CTS8-LZ12#TRPBF is relatively simple. A digital input signal is converted into an equivalent analog output signal using an array of resistors and capacitors. The analog output signal is then converted into an electrical voltage that can be read by the application circuitry. The digital input signal representing the analog output is first converted into a set of digital words. This set of digital words is then converted into a time sequence of analog voltages by using an internal DAC array. The outputs of the DAC array are then passed through low-pass filter and output amplifier circuits to produce a single analog voltage.

The LTC2632CTS8-LZ12#TRPBF includes an integrated low-noise, low-distortion, buffered voltage output driver that can source and sink up to 20 mA of current. The output driver is capable of driving a variety of loads and can be used to drive current into either single-ended (grounded load) or differential loads. The device has an integrated power management system that is used to reduce power consumption when the device is idle. The device can be operated in a low-power standby mode at 1 μA and still maintain full accuracy. The power-down feature enables the user to select the amount of time required to ramp up to operating level or to reach full accuracy after devices have been powered up.
