The LTC2640HTS8-HZ12#TRMPBF is an 8-bit multiplying digital-to-analog converter (MDAC) sub family member in Linear Technology\'s growing library of digital-to-analog converters. This family of DACs provides a combination of high performance and low power consumption in space and performance-constrained applications. The LTC2640HTS8-HZ12#TRMPBF is a monolithic integrated circuit optimized for industrial and consumer applications that require low-dropout and/or low-noise power supplies, such as battery-powered systems.

The device typically converts 8-bit digital words into analog voltages. It is a "chopper-stabilized" architecture that provides low noise and very low DC offset. Data output formats are voltage, current or calibrated temperature. The device is highly characterized and is specified over the full industrial temperature range of -40oC to +85oC.

The LTC2640HTS8-HZ12#TRMPBF draws less than 65μA under static loads and is able to reduce its own power consumption by entering a low-power shutdown mode. The device is protected against latch-up and false outputs due to electrostatic discharge. An internal reference clock allows the device to operate from a single clock frequency, resulting in increased circuit efficiency. It also features high-speed computation and output grayscale coding.

There are two major application areas for the LTC2640HTS8-HZ12#TRMPBF. The first is in Data Acquisition applications. The DAC is used to generate accurate voltages and currents that can be used to control data acquisition hardware, such as transducers, signal generators and actuators. The DAC can also be used as a constant current source, with an external precision resistor, to provide precise current sinks or sources.

The second major application area is in Automation and Robotics applications. The DAC can be used to generate precise position, torque and speed control outputs for servomotors and stepper motors in robotics and automation projects. The DAC also provides digital control of servomechanisms to obtain superior stability and accuracy.

In general, the LTC2640HTS8-HZ12#TRMPBF is a highly accurate DAC that is well-suited for industrial and consumer applications that require low-noise and/or low-dropout power supplies. Its low power design makes it an ideal choice for battery powered systems. The device is robustly designed, with built-in protection against latch-up and false out due to electrostatic discharge. It is also highly characterized and has a full industrial temperature range of -40oC to +85 oC.
