LTC2640CTS8-LZ8#TRMPBF

Overview

The LTC2640CTS8-LZ8#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 2.5V full-scale output and operates on a single 2.7V to 5.5V supply. The device utilizes a 3-wire SPI/MICROWIRE compatible interface with clock rates up to 50MHz. Key specifications include a maximum integral nonlinearity (INL) of ±0.5 LSB, a typical settling time of 3.2µs at 3V, and low power consumption of 180µA at 3V. It incorporates a power-on reset circuit that defaults the output to zero-scale.

Feature Summary

Integrated 10ppm/°C precision reference with 2.5V full-scale output
Rail-to-rail output buffer guaranteed monotonic over temperature
Asynchronous DAC Clear pin (Pin 8) for immediate zero-scale reset
Power-on reset to zero-scale upon initial power application

Applications

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

Procurement Notes

Verify the specific ordering suffix #TRMPBF indicates a 500-piece tape and reel packaging quantity. Confirm the 'C' grade corresponds to the commercial operating temperature range of 0°C to 70°C. Ensure the 'Z' suffix is selected if an asynchronous clear function is required for system initialization.

Selection Notes

Select this part when an 8-bit resolution is sufficient for the application's accuracy requirements. The LTC2640-L variant is appropriate for supplies between 2.7V and 5.5V. Choose the 'Z' suffix version if hardware-level zeroing via the CLR pin is necessary, as opposed to the 'M' suffix which resets to mid-scale.

Part Context

This component belongs to the LTC2640 family of single-channel DACs available in 8-, 10-, and 12-bit resolutions. The LTS8 package denotes an 8-lead plastic TSOT-23 form factor. The 'L' designation specifies the internal reference voltage level of 2.5V, distinguishing it from the 'H' grade which provides 4.096V.
