The LTC2635HMSE-LMI12#TRPBF broadly refers to the data acquisition field and more specifically to the class of digital-to-analog-converters (DAC). This particular family of device provides 12-bit resolution, rail-to-rail voltage output, and a wide operating range of up to 85-V supply.

Overview

These intensively-integrated ICs incorporate the latest technologies, provides excellent precision and accuracy, and are designed to meet the highest quality standards. Additionally, these devices are very easy to use and can be quickly integrated into any existing layout.

The LTC2635HMSE-LMI12#TRPBF family of chip is available in different package types, namely LLP (3mm × 5mm long-lead-length plastic) and MSOP (mini-small-outline-package) and comes with various voltage operating ranges. They are capable of operating over a wide temperature range from -40°C to +125°C and are housed in a hermetic package.

Features

The LTC2635HMSE-LMI12#TRPBF is has following features:

• Highly accuracy and precision 12 bit resolution
• Polarity configurations available
• Operating from 2.5 V to 85 V supply range
• Operating from -40°C to 125°C temperature range
• Low dropout (LDO) or extended temperature range op-amps and comparators available
• Small 4-WireSerial Interface protocol compatible with SPI compatible bus
• Wide range of pin configurations available with both SMD and through-hole packages

Working Principle

Depending on the application, the LTC2635HMSE-LMI12#TRPBF depends on the configuration of the integral op-amps and/or comparators. They require an external reference voltage and generate an analog output voltage that is proportional to the input digital word.

The LTC2635HMSE-LMI12#TRPBF provided four specific input commands and follows the standard SPI compatible 4-Wire, serial interface protocol. They require at least one clock pulse per operation and the use of control pins to select either write of read. After receiving the data from the bus, it will convert it accurately to a corresponding analog output.

Furthermore, the combination of auto-shutdown and active power-down feature makes this device a very energy efficient DAC chip. When the output voltage is equal to the reference voltage, the device will enter auto-shutdown mode and the device enters active power-down feature when the DAC voltage is not needed.

Applications

The LTC2635HMSE-LMI12#TRPBF are mainly used in DAC applications including:

• Data acquisition systems
• Industrial automation and control systems
• Precision instruments
• Programmable gain amplifiers
• Security systems
• High performance audio systems
• High speed analog-to-digital converters
• Sensors, such as temperature sensors
• Master-slave DAC systems

Conclusion

The LTC2635HMSE-LMI12#TRPBF is a versatile data-acquisition chip ideal for a wide range of applications. It is highly precise and accurate and requires minimal system resources. Additionally, its advanced auto-shutdown and active power-down features ensure energy efficiency.
