LTC2640ITS8-HM8#TRMPBF

Overview

The LTC2640ITS8-HM8#TRMPBF is a single-channel, 8-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features an integrated precision reference providing a full-scale output of 4.096V and operates on a single 4.5V to 5.5V supply. The device includes a rail-to-rail output buffer guaranteed monotonic over temperature. It utilizes a 3-wire SPI/MICROWIRE compatible serial interface with clock rates up to 50MHz. Key specifications include a typical settling time of 4.2µs at ±1LSB, a maximum integral nonlinearity (INL) of ±1LSB, and power consumption of 200µA at 3V equivalent operation. The unit is housed in an 8-lead TSOT-23 package.

Feature Summary

Integrated 10ppm/°C precision reference yielding 4.096V full-scale output
Rail-to-rail output buffer guaranteed monotonic over the operating temperature range
3-wire SPI/MICROWIRE compatible serial interface supporting clock rates up to 50MHz
Power-on reset to mid-scale code upon power-up

Applications

Mobile communications systems
Process control and industrial automation
Automatic test equipment
Portable battery-powered equipment
Optical networking devices

Procurement Notes

Verify the specific suffix #TRMPBF indicates a 500-piece tape and reel packaging configuration as defined in the manufacturer's ordering guide. Confirm that the H-grade designation matches the required automotive temperature range of –40°C to 125°C for the target application environment.

Selection Notes

Select this part when a 4.096V internal reference is required alongside an 8-bit resolution. Ensure the system supply voltage remains within the 4.5V to 5.5V range specified for the H-grade variant. Consider the HM suffix if a mid-scale power-on reset state is preferred over zero-scale initialization for downstream circuit protection.

Part Context

This component belongs to the LTC2640 family of single DACs available in 8-, 10-, and 12-bit resolutions. The 'H' grade denotes the extended temperature range suitable for automotive applications, while the 'M' suffix specifies the mid-scale power-on reset behavior. The 'TS8' indicates the 8-lead ThinSOT plastic package format.
