DS1050Z-005+TR

Overview

The DS1050Z-005+TR is a programmable timer integrated circuit from the DS1050Z series, manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 2.7 V to 5.5 V and draws a typical supply current of 50 µA. The device generates a fixed output frequency of 5 kHz with a maximum duty cycle of 50%. Designed for surface-mount installation, it is housed in an 8-SOIC package (0.154" width). The component supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Fixed 5 kHz output frequency generation
• Low power consumption with 50 µA supply current
• Wide supply voltage operation from 2.7 V to 5.5 V
• Available in 8-SOIC surface-mount package

Applications

• Programmable pulse-width modulation control
• DC motor speed regulation circuits
• LCD LED backlight dimming systems

Procurement Notes

Verify the suffix designation against official manufacturer documentation to confirm the specific tape-and-reel packaging configuration. Ensure the part number matches the exact frequency specification required for the design. Cross-reference the RoHS compliance status using the manufacturer's environmental declarations prior to procurement.

Selection Notes

Select this component when a fixed 5 kHz clock signal is required for timing or PWM applications. Confirm that the 8-SOIC footprint aligns with the PCB layout constraints. Verify that the 2.7 V to 5.5 V supply range is compatible with the system power rails and that the -40°C to +85°C industrial temperature range meets the operational environment requirements.

Part Context

This part belongs to the DS1050Z family of 5-bit programmable pulse-width modulators. Other variants in the series offer different fixed frequencies, such as the DS1050Z-025+ for 25 kHz output or the DS1050Z-001+ for 1 kHz output. All members share similar electrical characteristics and package options.

Replacement Considerations

Direct substitutes within the same family include DS1050Z-001+T&R and DS1050Z-025+T&R, provided the frequency difference is acceptable for the application.
